There are a couple of '$(git rev-parse --<opt>)' command substitutions
in __git_ps1() and three of them are executed in the main code path:
- the first to get the path to the .git directory ('--git-dir'),
- the second to check whether we're inside the .git directory
('--is-inside-git-dir'),
- and the last, depending on the results of the second, either
* to check whether it's a bare repo ('--is-bare-repository'), or
* to check whether inside a work tree ('--is-inside-work-tree').
Naturally, this imposes the overhead of fork()ing three subshells and
fork()+exec()ing three git commands.
Combine these four 'git rev-parse' queries into a single one and use
bash parameter expansions to parse the combined output, i.e. to
separate the path to the .git directory from the true/false of
'--is-inside-git-dir', etc. This way we can eliminate two of the
three subshells and git commands.

__git_ps1() runs the '$(git symbolic-ref HEAD)' command substitution
to find out whether we are on a branch and to find out the name of
that branch. This imposes the overhead of fork()ing a subshell and
fork()+exec()ing a git process.
Since HEAD is in most cases a single-line file and the symbolic ref
format is quite simple to recognize and parse, read and parse it using
only bash builtins, thereby sparing all that fork()+exec() overhead.
Don't display the git prompt if reading HEAD fails, because a readable
HEAD is required for a git repository. HEAD can also be a symlink
symbolic ref (due to 'core.preferSymlinkRefs'), so use bash builtins
for reading HEAD only when HEAD is not a symlink.

During an ongoing interactive rebase __git_ps1() finds out the name of
the rebased branch, the total number of patches and the number of the
current patch by executing a '$(cat .git/rebase-merge/<FILE>)' command
substitution for each. That is not quite the most efficient way to
read single line single word files, because it imposes the overhead of
fork()ing a subshell and fork()+exec()ing 'cat' several times.
Use the 'read' bash builtin instead to avoid those overheads.

__git_ps1() finds out the path to the repository by using the
__gitdir() helper function. __gitdir() is basically just a wrapper
around 'git rev-parse --git-dir', extended with support for
recognizing a remote repository given as argument, to use the path
given on the command line, and with a few shortcuts to recognize a git
repository in cwd or at $GIT_DIR quickly without actually running 'git
rev-parse'. However, the former two is only necessary for the
completion script but makes no sense for the bash prompt, while the
latter shortcuts are performance optimizations __git_ps1() can do
without (they just avoid the overhead of fork()+exec()ing a git
process).
Run 'git rev-parse --git-dir' directly in __git_ps1(), because it will
allow this patch series to combine several $(git rev-parse ...)
command substitutions in the main code path, and the overall
performance benefit will far outweigh the loss of those few shortcuts
in __gitdir(). Furthermore, since __gitdir() is not needed anymore
for the prompt, remove it from the prompt script finally eliminating
its duplication between the prompt and completion scripts. Also
remove the comment from the completion script warning about this code
duplication.

When describing a detached HEAD according to the $GIT_PS1_DESCRIBE
environment variable fails, __git_ps1() runs 'cut -c1-7 .git/HEAD' to
show the 7 hexdigits abbreviated commit object name in the prompt.
Obviously, this neither respects core.abbrev nor produces a unique
object name.
Fix this by using 'git rev-parse --short HEAD' instead and adjust the
corresponding test to use non-standard number of hexdigits.

Currently __gitdir() is duplicated in the git completion and prompt
scripts, while its tests are in the prompt test suite. This patch
series is about to change __git_ps1() in a way that it won't need
__gitdir() anymore and __gitdir() will be removed from the prompt
script.
So move all __gitdir() tests from the prompt test suite over to the
completion test suite. Update the setup tests so that they perform
only those steps that are necessary for each test suite.

This reverts commit 1a22bd31f0, reversing
changes made to 3e7a5b489e.
It makes it impossible to "git commit" when status.short is set, and
also "git status --porcelain" output is affected by status.branch.
Now that the "checkout" invoked internally from "rebase -i" knows to
honor GIT_REFLOG_ACTION, we can start to use it to write a better
reflog message when "rebase anotherbranch", "rebase --onto branch",
etc. internally checks out the new fork point. We will write:
rebase -i: checkout master
instead of the old
rebase -i
As all the calls git-rebase--interactive make to underlying git
commands that leave reflog messages are preceded by the internal
comment_for_reflog helper function, which uses the original value of
the GIT_REFLOG_ACTION variable it saw when it first started, the new
assignments to GIT_REFLOG_ACTION actively contaminate the value of
the variable, knowing that it will be reset to a sane value before
it is used again. This does not generally hold true but it should
suffice for now.

Commit 178e1de (fast-import: don't allow 'ls' of path with empty
components, 2012-03-09) restricted paths which:
. contain an empty directory component (e.g. foo//bar is invalid),
. end with a directory separator (e.g. foo/ is invalid),
. start with a directory separator (e.g. /foo is invalid).
However, the implementation also caught the empty path, which should
represent the root tree. Relax this restriction so that the empty path
is explicitly allowed and refers to the root tree.

Appending "--diff-algorithm=histogram" at the end of canned command
line for various modes of "diff" is correct for most of them but not
for "stash" that has a non-option already wired in, like so:
'stash' => {
DIFF => 'diff-index -p HEAD',
Appending an extra option after non-option may happen to work due to
overly lax command line parser, but that is not something we should
rely on. Instead, splice in the extra argument immediately after the
command name (i.e. 'diff-index', 'diff-files', etc.).

With the new --valgrind-parallel=<n> option, we support running the
tests in a single test script under valgrind in parallel using 'n'
processes.
This really follows the dumbest approach possible, as follows:
* We spawn the test script 'n' times, using a throw-away
TEST_OUTPUT_DIRECTORY. Each of the instances is given options that
ensures that it only runs every n-th test under valgrind, but
together they cover the entire range.
* We add up the numbers from the individual tests, and provide the
usual output.
This is really a gross hack at this point, and should be improved. In
particular we should keep the actual outputs somewhere more easily
discoverable, and summarize them to the user.
Nevertheless, this is already workable and gives a speedup of more
than 2 on a dual-core (hyperthreaded) machine, using n=4. This is
expected since the overhead of valgrind is so big (on the order of 20x
under good conditions, and a large startup overhead at every git
invocation) that redundantly running the non-valgrind tests in between
is not that expensive.

With the new --verbose-only=<pattern> option, one can enable --verbose
at a per-test granularity. The pattern is matched against the test
number, e.g.
./t0000-basic.sh --verbose-only='2[0-2]'
to see only the full output of test 20-22, while showing the rest in the
one-liner format.
As suggested by Jeff King, this takes care to wrap the entire
test_expect_* block, but nothing else, in the verbose toggling. We
can use the test_start/end functions from the previous commit for the
purpose.

t0000 contains some light self-tests of test-lib.sh, but --verbose was
not covered. Add a test.
The only catch is that the presence of a test harness influences the
output (specifically, the presence of some empty lines). So we need
to unset TEST_HARNESS or set it to a known value. Leaving it unset
leads to spurious test failures in the final summary, which come from
the subtest. So we always set it.

of read_branches_file() is remote_get_1(); the calling codepath is

- Indent the test body.
- Make sure that all lines end with &&, to make it easier to spot
breaks in the chain.
- When executing something in a subshell, put the parenthesis on
separate lines and indent the body. Also make sure that the
first statement in the subshell is a 'cd'.
- When redirecting input or output, do not use SP between
redirection operator and the target filename.
- Use the <<-\EOF and <<-EOF forms of heredoc, not <<EOF, when the
command is indented and the heredoc text itself does not have to
have a leading tab.
