This adds more proper rename detection limits. Instead of just checking
the limit against the number of potential rename destinations, we verify
that the rename matrix (which is what really matters) doesn't grow
ridiculously large, and we also make sure that we don't overflow when
doing the matrix size calculation.
This also changes the default limits from unlimited, to a rename matrix
that is limited to 100 entries on a side. You can raise it with the config
entry, or by using the "-l<n>" command line flag, but at least the default
is now a sane number that avoids spending lots of time (and memory) in
situations that likely don't merit it.
The choice of default value is of course very debatable. Limiting the
rename matrix to a 100x100 size will mean that even if you have just one
obvious rename, but you also create (or delete) 10,000 files, the rename
matrix will be so big that we disable the heuristics. Sounds reasonable to
me, but let's see if people hit this (and, perhaps more importantly,
actually *care*) in real life.

The way things are set up, you can now pass a "pathspec" to the
"read_directory()" function. If you pass NULL, it acts exactly
like it used to do (read everything). If you pass a non-NULL
pointer, it will simplify it into a "these are the prefixes
without any special characters", and stop any readdir() early if
the path in question doesn't match any of the prefixes.
NOTE! This does *not* obviate the need for the caller to do the *exact*
pathspec match later. It's a first-level filter on "read_directory()", but
it does not do the full pathspec thing. Maybe it should. But in the
meantime, builtin-add.c really does need to do first
read_directory(dir, .., pathspec);
if (pathspec)
prune_directory(dir, pathspec, baselen);
ie the "prune_directory()" part will do the *exact* pathspec pruning,
while the "read_directory()" will use the pathspec just to do some quick
high-level pruning of the directories it will recurse into.

There were instances of strncmp() that were formatted improperly

that caused the earlier mechanical conversion step to miss
them. This step cleans them up.

This mechanically converts strncmp() to use prefixcmp(), but only when
the parameters match specific patterns, so that they can be verified
easily. Leftover from this will be fixed in a separate step, including
idiotic conversions like
if (!strncmp("foo", arg, 3))
=>
if (!(-prefixcmp(arg, "foo")))
This was done by using this script in px.perl
#!/usr/bin/perl -i.bak -p
if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) {
s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|;
}
if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) {
s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|;
}
and running:
$ git grep -l strncmp -- '*.c' | xargs perl px.perl

Suggesting the use of [-a|-i|-o] with git-commit is unnecessarily

If you do:
$ /bin/rm foo
$ git status
we used to say "git add ... to add content to commit". But
suggsting "git add" to record the deletion of a file is simply
insane.
So this rewords various things:
- The section header is the old "Changed but not updated",
instead of "Changed but not added";
- Suggestion is "git add ... to update what will be committed",
instead of "... to add content to commit";
- If there are removed paths, the above suggestion becomes "git
add/rm ... to update what will be committed";
- For untracked files, the suggestion is "git add ... to
include in what will be committed".

This is a mechanical clean-up of the way *.c files include
system header files.
(1) sources under compat/, platform sha-1 implementations, and
xdelta code are exempt from the following rules;
(2) the first #include must be "git-compat-util.h" or one of
our own header file that includes it first (e.g. config.h,
builtin.h, pkt-line.h);
(3) system headers that are included in "git-compat-util.h"
need not be included in individual C source files.
(4) "git-compat-util.h" does not have to include subsystem
specific header files (e.g. expat.h).

Now that 'git add' is considered a first-class UI for 'update-index'
and that the 'git add' documentation states "Even modified files
must be added to the set of changes about to be committed" we should
make the output of 'git status' align with that documentation and
common usage.
So now we see a status output such as:
# Added but not yet committed:
# (will commit)
#
# new file: x
#
# Changed but not added:
# (use "git add file1 file2" to include for commit)
#
# modified: x
#
# Untracked files:
# (use "git add" on files to include for commit)
#
# y
which just reads better in the context of using 'git add' to
manipulate a commit (and not a checkin, whatever the heck that is).
We also now support 'color.status.added' as an alias for the existing
'color.status.updated', as this alias more closely aligns with the
current output and documentation.

If a user modifies files and runs 'git commit' (without the very
useful -a option) and they have not yet updated the index they
are probably coming from another SCM-like tool which would perform
the same as 'git commit -a' in this case. Showing the user their
current status and a final line of "nothing to commit" is not very
reassuring, as the user might believe that Git did not recognize
their files were modified.
Instead we can suggest as part of the 'nothing to commit' message
that the user invoke 'git add' to add files to their next commit.

While adding colour to the branch command it was pointed out that a
config option like "branch.color" conflicts with the pre-existing
"branch.something" namespace used for specifying default merge urls and
branches. The suggested solution was to flip the order of the
components to "color.branch", which I did for colourising branch.
This patch does the same thing for
- git-log (color.diff)
- git-status (color.status)
- git-diff (color.diff)
- pager (color.pager)
I haven't removed the old config options; but they should probably be
deprecated and eventually removed to prevent future namespace
collisions. I've done this deprecation by changing the documentation
for the config file to match the new names; and adding the "color.XXX"
options to contrib/completion/git-completion.bash.
Unfortunately git-svn reads "diff.color" and "pager.color"; which I
don't like to change unilaterally.

This brings the power of the index up front using a proper mental model
without talking about the index at all. See for example how all the
technical discussion has been evacuated from the git-add man page.
Any content to be committed must be added together. Whether that
content comes from new files or modified files doesn't matter. You
just need to "add" it, either with git-add, or by providing
git-commit with -a (for already known files only of course).
No need for a separate command to distinguish new vs modified files
please. That would only screw the mental model everybody should have
when using GIT.
