* Document the behavior of commit_lock_file() when it fails, namely
that it rolls back the lock_file object and sets errno
appropriately.
* Document the behavior of rollback_lock_file() when called for a
lock_file object that has already been committed or rolled back,
namely that it is a NOOP.

If closing an open lockfile fails, then we cannot be sure of the
contents of the lockfile, so there is nothing sensible to do but
delete it. This change also insures that the lock_file object is left
in a defined state in this error path (namely, unlocked).
The only caller that is ultimately affected by this change is
try_merge_strategy() -> write_locked_index(), which can call
close_lock_file() via various execution paths. This caller uses a
static lock_file object which previously could have been reused after
a failed close_lock_file() even though it was still in locked state.
This change causes the lock_file object to be unlocked on failure,
thus fixing this error-handling path.

It was previously a bug to call commit_lock_file() with a lock_file
object that was not active (an illegal access would happen within the
function). It was presumably never done, but this would be an easy
programming error to overlook. So before continuing, do a consistency
check that the lock_file object really is locked.

Sometimes users want to report a bug they experience on their

The macro ALLOC_GROW manages several aspects of dynamic memory
allocations for arrays: It performs overprovisioning in order to avoid
reallocations in future calls, updates the allocation size variable,
multiplies the item size and thus allows users to simply specify the
item count, performs the reallocation and updates the array pointer.
Sometimes this is too much. Add the macro REALLOC_ARRAY, which only
takes care of the latter three points and allows users to specfiy the
number of items the array can store. It can increase and also decrease
the size. Using the macro avoid duplicating the variable name and
takes care of the item sizes automatically.

Current syntax description makes one wonder if there is any
syntactic way to distinguish between <branch> and <upstream> so that
one can specify <branch> but not <upstream>, but that is not the
case.
Make it explicit that these arguments are positional, i.e. the
earlier ones cannot be omitted if you want to give later ones.

If the stderr of "git credential-cache" is redirected to a
pipe, the reader on the other end of a pipe may be surprised
that the pipe remains open long after the process exits.
This happens because we may auto-spawn a daemon which is
long-lived, and which keeps stderr open.
We can solve this by redirecting the daemon's stderr to
/dev/null once we are ready to go into our event loop. We
would not want to do so before then, because we may want to
report errors about the setup (e.g., failure to establish
the listening socket).
This does mean that we will not report errors we encounter
for specific clients. That's acceptable, as such errors
should be rare (e.g., clients sending buggy requests).
However, we also provide an escape hatch: if you want to see
these later messages, you can provide the "--debug" option
to keep stderr open.

Git's "ISO" date format does not really conform to the ISO 8601
standard due to small differences, and it cannot be parsed by ISO
8601-only parsers, e.g. those of XML toolchains.
The output from "--date=iso" deviates from ISO 8601 in these ways:
- a space instead of the `T` date/time delimiter
- a space between time and time zone
- no colon between hours and minutes of the time zone
Add a strict ISO 8601 date format for displaying committer and
author dates. Use the '%aI' and '%cI' format specifiers and add
'--date=iso-strict' or '--date=iso8601-strict' date format names.
