Now that people are really likely to start using separate remotes
(due to the default in git-clone changing) we should support ref
completion for these refs in as many commands as possible.

While we are working on this routine we should use for-each-ref
to obtain a list of local refs, as this should run faster than
peek-remote as it does not need to dereference tag objects in
order to produce the list of refs back to us.  It should also
be more friendly to users of StGIT as we won't generate a list
of the StGIT metadata refs.

Typing out options to git log/show/whatchanged can take a while, but

As git-rebase is a popular command bash should know how to complete
reference names and its long options.  We only support completions
which make sense given the current state of the repository, that
way users don't get shown --continue/--skip/--abort on the first
execution.

Also added support for long option --strategy to git-merge, as I
missed that option earlier and just noticed it while implementing
git-rebase.

Provide completion for currently known long options supported by
git-format-patch as well as the revision list specification argument,
which is generally either a refname or in the form a..b.

Since _git_log was the only code that knew how to complete a..b, but
we want to start adding option support to _git_log also refactor the
a..b completion logic out into its own function.

Many users want to display the current branch name of the current git
repository as part of their PS1 prompt, much as their PS1 prompt might
also display the current working directory name.

We don't force our own PS1 onto the user.  Instead we let them craft
their own PS1 string and offer them the function __git_ps1 which they
can invoke to obtain either "" (when not in a git repository) or
"(%s)" where %s is the name of the current branch, as read from HEAD,
with the leading refs/heads/ removed.

Users generally are not going to need to invoke plumbing-level commands
from within one line shell commands.  If they are invoking these commands
then it is likely that they are glueing them together into a shell script
to perform an action, in which case bash completion for these commands is
of relatively little use.

Now that git-merge is high-level Porcelain users are going to expect
to be able to use it from the command line, in which case we really
should also be able to complete ref names as parameters.

I'm also including completion support for the merge strategies
that are supported by git-merge.sh, should the user wish to use a
different strategy than their default.

Use "git show-ref --dereference" instead of "git peek-remote
$projectroot/project" in git_get_references. git-show-ref is faster
than git-peek-remote (40ms vs 56ms user+sys for git.git repository);
even faster is reading info/refs file (if it exists), but the
information in info/refs can be stale; that and the fact that
info/refs is meant for dumb protocol transports, not for gitweb.

git-show-ref is available since v1.4.4; the output format is slightly
different than git-peek-remote output format, but we accept both.

Sometimes users are given only read access to a subtree inside a
repository, and git-svn could not read log information (and thus
fetch commits) when connecting a session to the root of the
repository.  We now start an SVN::Ra session with the full URL
of what we're tracking, and not the repository root as before.

This change was made much easier with a cleanup of
repo_path_split() usage as well as improving the accounting of
authentication batons.

This makes "git branch -D other_branch" work even when HEAD
points at a yet-to-be-born branch.

Earlier, we checked the HEAD ref for the purpose of "subset"
check even when the deletion was forced (i.e. not -d but -D).
Because of this, you cannot delete a branch even with -D while
on a yet-to-be-born branch.

With this change, the following sequence that now works:

	mkdir newdir && cd newdir
	git init-db
	git fetch -k $other_repo refs/heads/master:refs/heads/othre
	# oops, typo
	git branch other othre
	git branch -D othre

Most notably, the original code first copied refs/remotes/ that
remote side had to local, and overwrote them by mapping refs/heads/
from the remote when a dumb protocol transport was used.

This allows you to say

to delete the named remote branch.  The refspec $src:$dst means
replace the destination ref with the object known as $src on the

mean "No object" to delete the target.
