One of the most common uses of git_path() is to pass a
constant, like git_path("MERGE_MSG"). This has two
drawbacks:
1. The return value is a static buffer, and the lifetime
is dependent on other calls to git_path, etc.
2. There's no compile-time checking of the pathname. This
is OK for a one-off (after all, we have to spell it
correctly at least once), but many of these constant
strings appear throughout the code.
This patch introduces a series of functions to "memoize"
these strings, which are essentially globals for the
lifetime of the program. We compute the value once, take
ownership of the buffer, and return the cached value for
subsequent calls. cache.h provides a helper macro for
defining these functions as one-liners, and defines a few
common ones for global use.
Using a macro is a little bit gross, but it does nicely
document the purpose of the functions. If we need to touch
them all later (e.g., because we learned how to change the
git_dir variable at runtime, and need to invalidate all of
the stored values), it will be much easier to have the
complete list.
Note that the shared-global functions have separate, manual
declarations. We could do something clever with the macros
(e.g., expand it to a declaration in some places, and a
declaration _and_ a definition in path.c). But there aren't
that many, and it's probably better to stay away from
too-magical macros.
Likewise, if we abandon the C preprocessor in favor of
generating these with a script, we could get much fancier.
E.g., normalizing "FOO/BAR-BAZ" into "git_path_foo_bar_baz".
But the small amount of saved typing is probably not worth
the resulting confusion to readers who want to grep for the
function's definition.

git-subtree's log format string uses "%ad" and "%cd", which
respect the user's configured log.date value.
This is problematic for git-subtree because it needs to use real
dates so that copied commits come through unchanged.
Add a test and tweak the format strings to use %aD and %cD
so that the default date format is used instead.

If the untracked status indicator is enabled, __git_ps1() looks for
untracked files by running 'git ls-files'. This can be perceptibly slow
in case of an untracked directory containing lot of files, because it
lists all files found in the untracked directory only to be redirected
into /dev/null right away (this is the actual command run by __git_ps1()):
$ ls untracked-dir/ |wc -l
100000
$ time git ls-files --others --exclude-standard --error-unmatch \
-- ':/*' >/dev/null 2>/dev/null
real 0m0.955s
user 0m0.936s
sys 0m0.016s
Eliminate this delay by additionally passing the '--directory
--no-empty-directory' options to 'git ls-files' to show only the name of
non-empty untracked directories instead of all their content:
$ time git ls-files --others --exclude-standard --directory \
--no-empty-directory --error-unmatch -- ':/*' >/dev/null 2>/dev/null
real 0m0.010s
user 0m0.008s

This fixes two instances where a &&-chain was broken in the subtree
tests and fixes a test error that was revealed because of this.
Many tests in t7900-subtree.sh make a commit and then use 'undo' to
reset the state for the next test. In the 'check hash of split' test,
an 'undo' was being invoked after a 'subtree split' even though the
particular invocation of 'subtree split' did not actually make a commit.
The subsequent check_equal was failing, but this failure was masked by
that broken &&-chain.
Removing this undo causes the failing check_equal to succeed but breaks
the a check_equal later on in the same test.
It turns out that an earlier test ('check if --message for merge works
with squash too') makes a commit but doesn't 'undo' to the state
expected by the remaining tests. None of the intervening tests cared
enough about the state of the test repo to fail and the spurious 'undo'
in 'check hash of split' restored the expected state for any remaining
test that might care.
Adding the missing 'undo' to 'check if --message for merge works
with squash too' and removing the spurious one from 'check hash of
split' fixes all tests once the &&-chains are completed.

At the beginning of the rewrite of git-pull.sh to C, we introduced a
redirection to git-pull.sh if the environment variable
_GIT_USE_BUILTIN_PULL was not defined in order to not break test scripts
that relied on a functional git-pull.
Now that all of git-pull's functionality has been re-implemented in
builtin/pull.c, remove this redirection, and retire the old git-pull.sh
into contrib/examples/.

To get the name of all config variables in a given section we perform a
'git config --get-regex' query for all config variables containing the
name of that section, and then filter its output through a case statement
to throw away those that though contain but don't start with the given
section.
Modify the regex to match only at the beginning, so the case statement
becomes unnecessary and we can get rid of it. Add a test to check that a
match in the middle doesn't fool us.

Currently there are a few completion functions that perform similar 'git
config' queries and filtering to get config variable names: the completion
of pretty aliases, aliases, and remote groups for 'git remote update'.
Unify those 'git config' queries in a helper function to eliminate code
duplication.
Though the helper functions to get pretty aliases and alieses are reduced
to mere one-liner wrappers around the newly added function, keep these
helpers still, because users' completion functions out there might depend
on them. And they keep their callers a tad easier to read, too.
Add tests for the pretty alias and alias helper to show that they work
as before; not for the remote groups query, though, because that's not
extracted into a helper function and it's not worth the effort to do so
for a sole callsite.

'echo -n' is not portable, but this script used it as a way to give
a string followed by a carriage return for progress messages.
Introduce a new helper shell function "progress" and use printf as a
more portable way to do this. As a side effect, this makes it
unnecessary to have a raw CR in our source, which can be munged in
some shells. For example, MsysGit trims CR before executing a shell
script file in order to make it work right on Windows even if it
uses CRLF as linefeeds.
While at it, replace "echo" using printf in debug() and say() to
eliminate the temptation of reintroducing the same bug.

During lazy-initialization of the lists of all commands and porcelain
commands the function __git_compute_all_commands() is called twice. The
relevant part of the call sequence looks like this:
__git_compute_porcelain_commands()
__git_compute_all_commands()
<finds list of all commands uninitialized>
__git_list_all_commands()
<initializes list of all commands>
__git_list_porcelain_commands()
__git_compute_all_commands()
<finds list of all commands already initialized, does nothing>
<filters porcelains from list of all commands>
Either one of the two calls could be removed and the initialization of
both command lists would still work as a whole, but let's remove the call
from __git_compute_porcelain_commands(), because this way
__git_list_porcelain_commands() will keep working in itself.

The completion script (in contrib/) contaminated global namespace

* ma/bash-completion-leaking-x:

differences, which meant that multi-byte characters can be chopped
in the middle. It learned to pay attention to character boundaries
(assuming the UTF-8 payload).
* jk/colors:
diff-highlight: do not split multibyte characters
When the input is UTF-8 and Perl is operating on bytes instead of
characters, a diff that changes one multibyte character to another
that shares an initial byte sequence will result in a broken diff
display as the common byte sequence prefix will be separated from
the rest of the bytes in the multibyte character.
For example, if a single line contains only the unicode character
U+C9C4 (encoded as UTF-8 0xEC, 0xA7, 0x84) and that line is then
changed to the unicode character U+C9C0 (encoded as UTF-8 0xEC,
0xA7, 0x80), when operating on bytes diff-highlight will show only
the single byte change from 0x84 to 0x80 thus creating invalid UTF-8
and a broken diff display.
Fix this by putting Perl into character mode when splitting the line
and then back into byte mode after the split is finished.
The utf8::xxx functions require Perl 5.8 so we require that as well.
Also, since we are mucking with code in the split_line function, we
change a '*' quantifier to a '+' quantifier when matching the $COLOR
expression which has the side effect of speeding everything up while
eliminating useless '' elements in the returned array.
