This function is a whole 26 bytes when compiled on x86_64, but is
currently invoked over 1.037 billion times when running pack-objects on
the Linux kernel git repository. This is hitting the point where
micro-optimizations do make a difference, and inlining it only increases
the object file size by 38 bytes.

As reported by perf, this dropped task-clock from 84183 to 83373 ms, and
total cycles from 223.5 billion to 221.6 billion. Not astronomical, but
worth getting for adding one word.

Remove the sample post-commit and post-receive hooks.  The sample
post-commit doesn't contain any sample functionality and the comments do
not provide more information than already found in the documentation.
The sample post-receive hooks doesn't provide any sample functionality
either and refers in the comments to a contrib hook that might be
installed in different locations on different systems, which isn't that
helpful.

Placing the contrib hooks into /usr/share/doc/ wasn't a good idea in the
first place.  According to the Debian policy they should be located in
/usr/share/git-core/, so let's put them there.

Fix another instance of a recursive merge incorrectly paying attention to

When running git describe --dirty the index should be refreshed.  Previously
the cached index would cause describe to think that the index was dirty when,
in reality, it was just stale.

The issue was exposed by python setuptools which hardlinks files into another
directory when building a distribution.

  t4014: clean up format.thread config after each test

The threading tests turn on format.thread, but never clean
up after themselves, meaning that later tests will also have
format.thread set.

This is more annoying than most leftover config, too,
because not only does it impact the results of other tests,
but it does so non-deterministically. Threading requires the
generation of message-ids, which incorporate the current
time, meaning a slow-running test script may generate
different results from run to run.

* ci/forbid-unwanted-current-branch-update:
  branch --set-upstream: regression fix

The "git branch" command, while not in listing mode, calls create_branch()
even when the target branch already exists, and it does so even when it is
not interested in updating the value of the branch (i.e. the name of the
commit object that sits at the tip of the existing branch). This happens
when the command is run with "--set-upstream" option.

The earlier safety-measure to prevent "git branch -f $branch $commit" from
updating the currently checked out branch did not take it into account,
and we no longer can update the tracking information of the current branch.

Minimally fix this regression by telling the validation code if it is
called to really update the value of a potentially existing branch, or if
the caller merely is interested in updating auxiliary aspects of a branch.

* ph/format-patch-no-color:
  format-patch: ignore ui.color

Allow git-svn to populate the svn:mergeinfo property automatically in
a narrow range of circumstances. Specifically, when dcommitting a
revision with multiple parents, all but (potentially) the first of
which have been committed to SVN in the same repository as the target
of the dcommit.

In this case, the merge info is the union of that given by each of the
parents, plus all changes introduced to the first parent by the other
parents.

In all other cases where a revision to be committed has multiple
parents, cause "git svn dcommit" to raise an error rather than
completing the commit and potentially losing history information in
the upstream SVN repository.

This behavior is disabled by default, and can be enabled by setting
the svn.pushmergeinfo config option.

commit c9bfb953 (want_color: automatically fallback to color.ui,
2011-08-17) introduced a regression where format-patch produces colorized
patches when color.ui is set to "always".

In f3aafa4d (Disable color detection during format-patch, 2006-07-09),
git_format_config was taught to intercept diff.color to avoid passing it
down to git_log_config and later, git_diff_ui_config.

Teach git_format_config to intercept color.ui in the same way.
