Since gitk looks for the HEAD commit to attach the fake commits for
local changes to, we can miss out on seeing the fake commits if we
have a path limit and the HEAD commit doesn't alter any of the files
in the path limit.
This fixes it by running
git rev-list -1 $head -- $paths
if we have a path limit, and taking the result of that as the commit
to attach the fake commits to. This means that we can be attaching
the fake commits to a different commit in each view, so we use a new
$viewmainhead($view) for that.
This also fixes a buglet where updatecommits would only fix up the
fake commits if the HEAD changed since the last call to updatecommits,
whereas it should fix them up if the HEAD has changed since this view
was last created or updated.

In Tcl, a comment in a switch command where a pattern would be expected
doesn't do what one would expect, so this moves the comments inside the

Occasionally gitk will throw a Tcl error complaining that linehtag(n)
is undefined when. It happens when the commit list is still growing
(e.g. when updating the commit list) and gitk is set to highlight
commits that affect certain file(s). What happens is that the changes
to the commit list set need_redisplay to indicate that the display
needs to be redrawn. That causes the next call to drawcommits to call
clear_display, which unsets iddrawn and thus ensures that readfhighlight
won't call bolden on any rows that have moved. However, it is possible
for readfhighlight to be called after the commit list has changed but
before drawcommits has run, meaning that readfhighlight will potentially
think that rows have been drawn when they haven't, because of the
change in the id -> row mapping (and the fact that iddrawn is indexed
by id but line[hnd]tag are indexed by row number).
This fixes it (and also optimizes things a little) by making bolden
and bolden_name check need_redisplay before doing anything. If
need_redisplay is set, then there is no point doing anything because
the whole display is about to get cleared and redrawn, and it avoids
looking up line[hn]tag using stale row numbers.

This commit fixes two problems with commit encodings:
1) git-log actually uses i18n.logoutputencoding to generate
its output, and falls back to i18n.commitencoding only
when that option is not set. Thus, gitk should use its
value to read the results, if available.
2) The readcommit function did not process encodings at all.
This led to randomly appearing misconverted commits if
the commit encoding differed from the current locale.
Now commit messages should be displayed correctly, except
when logoutputencoding is set to an encoding that cannot
represent charecters in the message. For example, it is
impossible to convert Japanese characters from Shift-JIS
to CP-1251 (although the reverse conversion works).
The reason for using git log to read the commit and then getting
Tcl to convert its output is that is essentially what happens in
the normal path through getcommitlines, hence there is less chance
for unintended differences in how commits are processed in
getcommitlines and do_readcommit.

Originally gitk required the user to specify all limiting

It is rather unfriendly for new users, who may not know
which options can be used, or, indeed, that it is possible
to specify them at all.
This commit modifies the dialog to present the most useful
options as individual fields. Note that options that may
be useful to an extent, but produce a severely broken view,
are deliberately not included.

This makes the "Show origin of this line" menu item work correctly
on the fake commits that gitk shows for local uncommitted changes.
With the fake commit for changes that aren't checked in to the index,
we can actually get a 3-way diff shown, which means we might have to
blame either the parent or the commit being merged in (which we get
from .git/MERGE_HEAD).
If the parent is the fake commit which shows the changes that have
been checked in to the index, then we need to get the SHA1 of the blob
for the version of the file that is in the index, then use git cat-file
blob to get the contents of the blob, and give that to git blame with --contents - so that git blame will do the blame on the index version
of the file. In that case, we might get the all-zeroes SHA1 back from
git blame, meaning that the line is new in the index version of the
file, so then we have to use $nullid2 (the pseudo-SHA1 of the fake
commit for the checked-in changes).

When walking back from the line where a right-click happened to the
previous hunk separator line to calculate the line number to work on,
we were counting every line including the one clicked on. That isn't
right; if the user clicked on the line immediately after the hunk
separator then the correct line number would be the one from the
hunk separator. Therefore this looks at the clicked-on line to work
out which parent to blame (or whether to blame the current commit),
and then looks only at the preceding lines to work out the offset from
the line number in the hunk separator.
This also fixes an off-by-one error when we are showing files rather
than diffs. In this case diff_menu_filebase is the line number of
the banner showing the file name, so the first line of the file is
at line $diff_menu_filebase + 1.
This also simplifies the code in find_hunk_blamespec a bit and arranges
that we don't pop up the context menu if the user clicks on a file
separator line or a hunk separator line.

This changes the link detection logic to accept strings of between 6
and 40 hex characters as a possible SHA1 ID of another commit, rather
than insisting on seeing the full 40 hex characters.
To make the logic that turns a possible link into an actual link work
with abbreviated IDs, this changes the way the commitinterest array is
used, and puts the code that deals with it in a pair of new functions.
The commitinterest array is now indexed by just the first 4 characters
of the interesting SHA1 ID, and each element is a list of id + command
pairs. This also pulls out the logic for expanding an abbreviated
SHA1 to the list of matching full IDs into its own function (the way
it is done is still the same slow way it was done before, which should
be improved some day).
This also fixes the bug where clicking on a link would take you to the
wrong commit if the line number of the target had changed since the
link was made.

This is the result of running make update-po and removing or fixing
the strings that were fuzzily matched. The ones that were fixed were
the ones where the only change was "git rev-list" to "git log", and
the "about gitk" message where the copyright year got updated.
To get xgettext to see the menu labels as needing translation, it
was necessary for arrange for them to be preceded by "mc". This
therefore changes makemenu to ignore the first element in each
menu item so that it can be "mc" in the makemenu call.

This is inspired by patches from Robin Rosenberg but takes a different
approach. This adds a "makemenu" procedure for constructing menus
that allows the menu layout to be specified in a clear fashion, and
provides one place where the alt+letter accelerators can be detected
and handled.
The alt+letter accelerator is specified by putting an ampersand (&)
before the letter for the accelerator in the menu item name. (Two
ampersands in succession produce one ampersand in the menu item as
it appears on screen.) This is handled in makemenu.
We also add an mca procedure which is like mc but also does the
ampersand translation, for use when we want to refer to a menu item
by name. The mca name and the locations where we use it were
shamelessly stolen from Robin Rosenberg's patch.
This doesn't actually add any alt+letter accelerators yet.

This adds an option allowing the user to select whether gitk should
look up per-file encoding settings using git check-attr or not. If
not, gitk uses the global encoding set in the git config (as reported
by git config --get gui.encoding) for all files, or if that is not
set, then the system encoding.
The option is controlled by a checkbox in the Edit->Preferences
window, and defaults to off for now because git check-attr is so
slow. When the user turns it on we discard any cached diff file
lists in treediffs, because we may not have encodings cached for
the files listed in those lists, meaning that getblobdiffline will
do it for each file, which will be really really slow.
This adjusts the limit of how many paths cache_gitattr passes to each
instance of git check-attr depending on whether we're running under
windows or not. Passing only 30 doesn't effectively amortize the
startup costs of git check-attr, but it's all we can do under windows
because of the 32k limit on arguments to a command. Under other OSes
we pass up to 1000.
Similarly we adjust how many lines gettreediffline processes depending
on whether we are doing per-file encodings so that we don't run for
too long. When we are, 500 seems to be a reasonable limit, leading
to gettreediffline taking about 60-70ms under Linux (almost all of
which is in cache_gitattr, unfortunately). This means that we can
take out the update call in cache_gitattr.
This adds a simple cache on [tclencoding]. Now that we get repeated
calls to translate the same encoding, this is useful.
This reindents the new code added in the last couple of commits to
conform to the gitk 4-space indent and makes various other improvements:
use regexp in gitattr and cache_gitattr instead of split + join + regsub,
make gui_encoding be the value from [tclencoding] to avoid having to
do [tcl_encoding $gui_encoding] in each call to get_path_encoding,
and print a warning message at startup if $gui_encoding isn't
supported by Tcl.

When the diff contains thousands of files, calling git-check-attr once
per file is very slow. With this patch gitk does attribute lookup in
batches of 30 files while reading the diff file list, which leads to a
very noticeable speedup.
It may be possible to reimplement this even more efficiently, if
git-check-attr is modified to support a --stdin-paths option.
Additionally, it should quote the ':' character in file paths, or
provide a more robust way of column separation.

This allows the encoding to be specified for file contents and used
when displaying files and diffs in the bottom-left pane. When
displaying diffs, the encoding for each diff hunk is that for the file
that the diff hunk is from, so it can change through the course of the
diff.
The encoding for file contents is determined as follows:
- File encoding defaults to the system encoding.
- It can be overridden by setting the gui.encoding option.
- Finally, the 'encoding' attribute is checked on
per-file basis; it has the last word.
Note: Since git-check-attr does not provide support for reading
attributes from trees, attribute lookup is done using files from the
working directory.
This also extends the range of supported encoding names, adding
ShiftJIS and Shift-JIS as aliases for Shift_JIS, and allowing
cp-*, cp_*, ibm-*, ibm_*, jis-* and jis_* as aliases for cp*,
ibm* and jis* respectively.
This also fixes some bugs in handling of non-ASCII filenames. Core
git apparently supports only locale-encoded filenames, so processing
is done using the system encoding.
