When two branches are merged that modify a subdirectory (possibly in
different intermediate steps) such that both end up identical, then
rev-list chooses only one branch. But when we filter history, we want to
keep both branches. Therefore, we must use --full-history.

We can use git rev-list --parents when we list the commits to rewrite.
It is not necessary to run git rev-list --parents for each commit in the
loop.

With git-filter-branch --subdirectory-filter <subdirectory> you can
get at the history, as seen by a certain subdirectory. The history
of the rewritten branch will only contain commits that touched that
subdirectory, and the subdirectory will be rewritten to be the new
project root.

Earlier, when the local repository has a branch "frotz" and the
remote repository has a tag "frotz" (but not branch "frotz"),
"git-push frotz" mistakenly updated the tag at the remote side.
This was because the partial refname matching code was applied
independently on both source and destination side.
With this fix, when a colon-less refspec is given to git-push,
we first match it with the refs in the source repository, and
update the matching ref in the destination repository.

When "git push A:B" is given, and A (or B) is not a full refname
that begins with refs/, we require an unambiguous match with an
existing ref. For this purpose, a match with a local branch or
a tag (i.e. refs/heads/A and refs/tags/A) is called a "strong
match", and any other match is called a "weak match". A partial
refname is unambiguous when there is only one strong match with
any number of weak matches, or when there is only one weak match
and no other match.
However, as reported by Sparse with Ramsay Jones recently,
count_refspec_match() function had a bug where a variable in an
inner block masked a different variable of the same name, which
caused the weak matches to be ignored.
This fixes it, and adds tests for the fix.

When checking what ref the source refspec matches, we have no
business setting the default for the destination, so move that
code lower. Also simplify the result from the code block that
matches the source side by making it set matched_src only upon
unambiguous match.

This does not change functionality; just splits one block that

In several of the text messages, the tense of the verb is inconsistent.
For example, "Add" vs "Creates". It is customary to use imperative for
command description.

Make git-cvsserver understand some options inspired by
git-daemon, namely --base-path, --export-all, --strict-paths.
Also allow the caller to specify a whitelist of allowed
directories, again similar to git-daemon.
While already adding option parsing also support the common
--help and --version options.
Rationale:
While the gitcvs.enabled configuration option already
offers means to limit git-cvsserver access to a repository,
there are some use cases where other methods of access
control prove to be more useful.
E.g. if setting up a pserver for a collection of public
repositories one might want limit the exported repositories
to exactly the directory this collection is located whithout
having to worry about other repositories that might lie around
with the configuration variable set (never trust your users ;)

The path submitted with the Root request has to be absolute
(cvs does it this way and it may save us some sanity checks
later)
If multiple roots are specified (e.g. because we use
pserver authentication which will already include the
root), ensure that they say all the same.
Probably neither is a security risk, and neither should ever
be triggered by a sane client, but when validating
input data, it's better to be save than sorry.

Define __slots__ for the Commit class. This reserves space in each Commit

This changes the Commit class to use new-style class, which has
been available since Python 2.2 (Dec 2001). This is a necessary
step in order to use __slots__[] declaration, so that we can
reduce the memory footprint in the next patch.

Although it is not advisable, we have always allowed a branch
and a tag to have the same basename (i.e. it is not illegal to
have refs/heads/frotz and refs/tags/frotz at the same time).
When talking about a specific commit, the interpretation of
'frotz' has always been "use tag and then check branch",
although we warn when ambiguities exist.
However "git checkout $name" is defined to (1) first see if it
matches the branch name, and if so switch to that branch; (2)
otherwise it is an instruction to detach HEAD to point at the
commit named by $name. We did not follow this definition when
$name appeared under both refs/heads/ and refs/tags/ -- we
switched to the branch but read the tree from the tagged commit,
which was utterly bogus.

Otherwise
git push 'remote-name' 'refs/heads/*:refs/remotes/other/*'
will consider references in "refs/heads" of the remote repository
"remote-name", instead of the ones in "refs/remotes/other", which
the given refspec clearly means.

The main window's diff header bar background switched from orange
to gold recently, and I liked the effect it had on readability of
the text. Since I wanted the blame viewer to match, here it is.
Though this probably should be a user defined color, or at least
a constant somewhere that everyone can reference.

i was off by one.
