Pushing into the currently checked out branch of a non-bare
repository can be dangerous; the HEAD then loses sync with
the index and working tree, and it looks in the receiving
repo as if the pushed changes have been reverted in the
index (since they were never there in the first place).
This patch adds a safety valve that checks for this
condition and either generates a warning or denies the
update. We trigger the check only on a non-bare repository,
since a bare repo does not have a working tree (and in fact,
pushing to the HEAD branch is a common workflow for
publishing repositories).
The behavior is configurable via receive.denyCurrentBranch,
defaulting to "warn" so as not to break existing setups
(though it may, after a deprecation period, switch to
"refuse" by default). For users who know what they are doing
and want to silence the warning (e.g., because they have a
post-receive hook that reconciles the HEAD and working
tree), they can turn off the warning by setting it to false
or "ignore".

Occasionally, it may be useful to prevent branches from getting deleted from
a centralized repository, particularly when no administrative access to the
server is available to undo it via reflog. It also makes
receive.denyNonFastForwards more useful if it is used for access control
since it prevents force-updating by deleting and re-creating a ref.

format-patch is most commonly used for multiple patches at once when
sending a patchset, in which case we want to number the patches; on
the other hand, single patches are not usually expected to be
numbered.
In other words, the typical behavior expected from format-patch is the
one obtained by enabling autonumber, so we set it to be the default.
Users that want to disable numbering for a particular patchset can do
so with the existing -N command-line switch. Users that want to
change the default behavior can use the format.numbering config key.

Cygwin's POSIX emulation allows use of core.filemode true, unlike native
Window's implementation of stat / lstat, and Cygwin/git users who have
configured core.filemode true in various repositories will be very
unpleasantly surprised to find that git is no longer honoring that option.
So, this patch forces use of Cygwin's stat functions if core.filemode is
set true, regardless of any other considerations.

lstat/stat functions in Cygwin are very slow, because they try to emulate
some *nix things that Git does not actually need. This patch adds Win32
specific implementation of these functions for Cygwin.
This implementation handles most situation directly but in some rare cases
it falls back on the implementation provided for Cygwin. This is necessary
for two reasons:
- Cygwin has its own file hierarchy, so absolute paths used in Cygwin is
not suitable to be used Win32 API. cygwin_conv_to_win32_path can not be
used because it automatically dereference Cygwin symbol links, also it
causes extra syscall. Fortunately Git rarely use absolute paths, so we
always use Cygwin implementation for absolute paths.
- Support of symbol links. Cygwin stores symbol links as ordinary using
one of two possible formats. Therefore, the fast implementation falls
back to Cygwin functions if it detects potential use of symbol links.
The speed of this implementation should be the same as mingw_lstat for
common cases, but it is considerable slower when the specified file name
does not exist.
Despite all efforts to make the fast implementation as robust as possible,
it may not work well for some very rare situations. I am aware only one
situation: use Cygwin mount to bind unrelated paths inside repository
together. Therefore, the core.ignoreCygwinFSTricks configuration option is
provided, which controls whether native or Cygwin version of stat is used.

With a new configuration "diff.mnemonicprefix", "git diff" shows the
differences between various combinations of preimage and postimage trees
with prefixes different from the standard "a/" and "b/". Hopefully this

"git diff" compares the (i)ndex and the (w)ork tree;
"git diff HEAD" compares a (c)ommit and the (w)ork tree;
"git diff --cached" compares a (c)ommit and the (i)ndex;
"git-diff HEAD:file1 file2" compares an (o)bject and a (w)ork tree entity;
"git diff --no-index a b" compares two non-git things (1) and (2).
Because these mnemonics now have meanings, they are swapped when reverse
diff is in effect and this feature is enabled.

The only reason we did not call "prune" in git-gc was that it is an
inherently dangerous operation: if there is a commit going on, you will
prune loose objects that were just created, and are, in fact, needed by the
commit object just about to be created.
Since it is dangerous, we told users so. That led to many users not even
daring to run it when it was actually safe. Besides, they are users, and
should not have to remember such details as when to call git-gc with
--prune, or to call git-prune directly.
Of course, the consequence was that "git gc --auto" gets triggered much
more often than we would like, since unreferenced loose objects (such as
left-overs from a rebase or a reset --hard) were never pruned.
Alas, git-prune recently learnt the option --expire <minimum-age>, which
makes it a much safer operation. This allows us to call prune from git-gc,
with a grace period of 2 weeks for the unreferenced loose objects (this
value was determined in a discussion on the git list as a safe one).
If you want to override this grace period, just set the config variable
gc.pruneExpire to a different value; an example would be
[gc]
pruneExpire = 6.months.ago
or even "never", if you feel really paranoid.
Note that this new behaviour makes "--prune" be a no-op.
While adding a test to t5304-prune.sh (since it really tests the implicit
call to "prune"), also the original test for "prune --expire" was moved
there from t1410-reflog.sh, where it did not belong.
