This patch teaches git stash branch to tolerate stash-like arguments.
In particular, a stash is only required if an argument isn't specified
and the stash is only dropped if a stash entry reference was
specified or implied.
The implementation has been simplified by taking advantage of
assert_stash_like() and the variables established by
parse_flags_and_rev().

git stash pop is abstracted into its own implementation function - pop_stash.
The behaviour is changed so that git stash pop fails early if the
the specified stash reference does not exist or does not refer to
an extant entry in the reflog of the reference stash.
This fixes the case where the apply succeeds, but the drop fails.
Previously this caused caused git stash pop to exit with a non-zero exit code
and a dirty tree.
Now, git stash pop fails with a non-zero exit code, but the working
tree is not modified.

Previously, git stash drop would fail noisily while executing git reflog
delete if the specified revision was not a stash reference.
Now, git stash drop fails with an error message which more precisely
indicates the reason for failure.
Furthermore, git stash drop will now fail with a non-zero status code
if stash@{n} specifies a stash log entry that does not actually exist.
This change in behaviour is achieved by delegating argument parsing
to the common parse_flags_and_rev() function (via a call to
assert_stash_ref).

This commit is required because git rev-parse in 1.7.2 does not correctly
indicate invalid log references using a non-zero status code.
We use a proxy for the condition (non-empty error output) as
a substitute. This commit can be reverted when, and if, rev-parse
is fixed to indicate invalid log references with a status code.

Introduce parse_flags_and_revs. This function requires that
there is at most one stash-like revision parameter and
zero or more flags.
It knows how to parse -q,--quiet and --index flags, but leaves
other flags parsed.
Specified revisions are checked to see that they are at
least stash-like (meaning: they look like something created
by git stash save or git stash create).
If this is so, then IS_STASH_LIKE is initialized to a non-empty value.
If the specified revision also looks like a stash log entry reference,
then IS_STASH_REF is initialized to a non-empty value.
References of the form ref@{spec} are required to precisely identify
an individual commit.
If no reference is specified, stash@{0} is assumed.
Once the specified reference is validated to be at least stash_like
an ensemble of derived variables, (w_commit, w_tree, b_commit, etc)
is initialized with a single call to git rev-parse.
Repeated calls to parse_flags_and_rev() avoid repeated calls
to git rev-parse if the specified arguments have already been
parsed.
Subsequent patches in the series modify the existing
git stash subcommands to make use of these functions
as appropriate.
An ensemble of supporting functions that make use of the state
established by parse_flags_and_rev(). These are described below:
The ancillary functions are:
is_stash_like(): which can be used to test
whether a specified commit looks like a commit created with
git stash save or git stash create.
assert_stash_like(): which can be used by
commands that misbehave unless their arguments stash-like.
is_stash_ref(): which checks whether an argument
is valid stash reference(e.g. is of the form
['refs/']stash['@{'something'}])
assert_stash_ref(): which can be used by commands
that misbehave unless their arguments are both stash-like and
refer to valid stash entries.

These two tests weren't about how "git reflog show <branch>" exits when
there is no reflog, but were about "checkout" and "branch" create or not
create reflog when creating a new <branch>. Update the tests to check
what we are interested in, using "git rev-parse --verify".
Also lose tests based on "test -f .git/logs/refs/heads/<branch>" from

The correct advice should have been taken from c289c31 (t/t7006: ignore

we experienced was with "unset", not with "export" (exporting an

The '!()' notation is interpreted as a pattern-list on Ksh. The Ksh man
page describe it as follows:
!(pattern-list)
Matches anything except one of the given patterns.
Ksh performs a file glob using the pattern-list and then tries to execute
the first file in the list. If a space is added between the '!' and the
open parens, then Ksh will not interpret it as a pattern list, but in this
case, it is preferred to use test_must_fail, so lets do so.

These two lines use the negation '!' operator to negate the result of a
simple command. Since these commands do not contain any pipes or other
complexities, the test_must_fail function can be used and is preferred
since it will additionally detect termination due to a signal.
This was noticed because the second use of '!' does not include a space
between the '!' and the opening parens. Ksh interprets this as follows:
!(pattern-list)
Matches anything except one of the given patterns.

Some have found the wording of the description to be somewhat ambiguous
with respect to when it is desirable to use test_must_fail instead of
"! <git-command>". Tweak the wording somewhat to hopefully clarify that
it is _because_ test_must_fail can detect segmentation fault that it is
desirable to use it instead of "! <git-command>".

Apparently using the Storable module during global destruction is
unsafe - there is a bug which can cause segmentation faults:
http://rt.cpan.org/Public/Bug/Display.html?id=36087http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=482355
The persistent memoization support introduced in commit 8bff7c538
relied on global destruction to write cached data, which was leading
to segfaults in some Perl configurations. Calling Memoize::unmemoize
in the END block forces the cache writeout to be performed earlier,
thus avoiding the bug.

Earlier we tried to make sure that the trees we get are what A...B
syntax produced, by checking that earlier ones are all marked
uninteresting (which has to be true as they are merge bases),
there are two remaining ones that are interesting, and they are
marked as non-symmetric-left and symmetric-left respectively.
The "the last two must be interesting" condition is however wrong when one
is an ancestor of the other between A and B (i.e. fast-forward). In such
a case, one of them is marked uninteresting.

73e25e7c (git --paginate: do not commit pager choice too early,
2010-06-26) failed to take some cases into account.
1b. Builtins that do not use RUN_SETUP (like git config) do
not find GIT_DIR set correctly when the pager is launched
from run_builtin(). So the core.pager configuration is
not honored from subdirectories of the toplevel for them.
4a. External git commands (like git request-pull) relied on the
early pager launch to take care of handling the -p option.
Ever since 73e25e7c, they do not honor the -p option at all.
4b. Commands invoked through ! aliases (like ls) were also relying
on the early pager launch.
Fix (4a) by launching the pager (if requested) before running such a
“dashed external”. For simplicity, this still does not search for a
.git directory before running the external command; when run from a
subdirectory of the toplevel, therefore, the “[core] pager”
configuration is still not honored.
Fix (4b) by launching pager if requested before carrying out such an
alias. Actually doing this has no effect, since the pager (if any)
would have already been launched in a failed attempt to try a
dashed external first. The choice-of-pager-not-honored-from-
subdirectory bug still applies here, too.
(1b) is not a regression. There is no need to fix it yet.

15b4f7a (merge-tree: use ll_merge() not xdl_merge(), 2010-01-16)
introduced a regression to merge-tree to cause it to segfault when merging
files which existed in one branch, but not in the other or in the
merge-base. This was caused by referencing entry->path at a time when
entry was known to be possibly-NULL.
To correct the problem, we save the path of the entry we came in with,
as the path should be the same among all the stages no matter which
sides are involved in the merge.
