Diffs that have been produced with textconv almost certainly
cannot be applied, so we want to be careful not to generate
them in things like format-patch.
This introduces a new diff options, ALLOW_TEXTCONV, which
controls this behavior. It is off by default, but is
explicitly turned on for the "log" family of commands, as
well as the "diff" porcelain (but not diff-* plumbing).
Because both text conversion and external diffing are
controlled by these diff options, we can get rid of the
"plumbing versus porcelain" distinction when reading the
config. This was an attempt to control the same thing, but
suffered from being too coarse-grained.

The original implementation of textconv put the conversion
into fill_mmfile. This was a bad idea for a number of
reasons:
- it made the semantics of fill_mmfile unclear. In some
cases, it was allocating data (if a text conversion
occurred), and in some cases not (if we could use the
data directly from the filespec). But the caller had
no idea which had happened, and so didn't know whether
the memory should be freed
- similarly, the caller had no idea if a text conversion
had occurred, and so didn't know whether the contents
should be treated as binary or not. This meant that we
incorrectly guessed that text-converted content was
binary and didn't actually show it (unless the user
overrode us with "diff.foo.binary = false", which then
created problems in plumbing where the text conversion
did _not_ occur)
- not all callers of fill_mmfile want the text contents. In
particular, we don't really want diffstat, whitespace
checks, patch id generation, etc, to look at the
converted contents.
This patch pulls the conversion code directly into
builtin_diff, so that we only see the conversion when
generating an actual patch. We also then know whether we are
doing a conversion, so we can check the binary-ness and free
the data from the mmfile appropriately (the previous version
leaked quite badly when text conversion was used)

These tests provide a basic sanity check that textconv'd
files work. The tests try to describe how this configuration
_should_ work; thus some of the tests are marked to expect
failure.
In particular, we fail to actually textconv anything because
the 'diff.foo.binary' config option is not set, which will
be fixed in the next patch.
This also means that some "expect_failure" tests actually
seem to be fixed; in reality, this is just because textconv
is broken and its failure mode happens to make these tests
work.

This patch also changes the term "custom diff driver" to
"external diff driver"; now that there are more facets of a
"custom driver" than just external diffing, it makes sense
to refer to the configuration of "diff.foo.*" as the "foo
diff driver", with "diff.foo.command" as the "external
driver for foo".

Previously, branches were listed on a single line in each section. But
if there are many branches, then horizontal, line-wrapped lists are very
inconvenient to scan for a human. This makes the lists vertical, i.e one
branch per line is printed.
Since "git remote" is porcelain, we can easily make this
backwards-incompatible change.

If a file is different between the working tree copy, the index, and the
HEAD, then we do not allow it to be deleted without --force.
However, this is overly tight in the face of "git add --intent-to-add":
$ git add --intent-to-add file
$ : oops, I don't actually want to stage that yet
$ git rm --cached file
error: 'empty' has staged content different from both the
file and the HEAD (use -f to force removal)
$ git rm -f --cached file
Unfortunately, there is currently no way to distinguish between an empty
file that has been added and an "intent to add" file. The ideal behavior
would be to disallow the former while allowing the latter.
This patch loosens the safety valve to allow the deletion only if we are
deleting the cached entry and the cached content is empty. This covers
the intent-to-add situation, and assumes there is little harm in not
protecting users who have legitimately added an empty file. In many
cases, the file will still be empty, in which case the safety valve does
not trigger anyway (since the content remains untouched in the working
tree). Otherwise, we do remove the fact that no content was staged, but
given that the content is by definition empty, it is not terribly
difficult for a user to recreate it.
However, we still document the desired behavior in the form of two
tests. One checks the correct removal of an intent-to-add file. The other
checks that we still disallow removal of empty files, but is marked as
expect_failure to indicate this compromise. If the intent-to-add feature
is ever extended to differentiate between normal empty files and
intent-to-add files, then the safety valve can be re-tightened.

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 based on a patch by Linus Torvalds, but totally rewritten by me.

06cbe855 (Make core.sharedRepository more generic, 2008-04-16) made
several testcases in t1301-shared-repo.sh which fail if on a system
which creates files with extended attributes (e.g. SELinux), since ls
appends a '+' sign to the permission set in such cases. In fact,
POSIX.1 allows ls to add a single printable character after the usual
3x3 permission bits to show that an optional alternate/additional access
method is associated with the path.
This fixes the testcase to strip any such sign prior to verifying the
permission set.
