Merge branch 'py/git-git-extra-stuff'

Some changes were added directly to git.git's git-gui subtree, instead
of being added to the separate git-gui repo and then being pulled back
into git.git. This means those changes are now not in the git-gui tree.
So pull them back into git-gui so we match with what git.git has (after
they pull in the recently added commits).

Most of the changes could be added back in via an octopus merge of all
the missing branches. But there were two commits (faf420e05a and
b71c6c3b64) which touched other parts of git.git along with git-gui, so
they had to be added back in via a cherry-pick because directly pulling
them in would also pull in all the ancestors of those commits,
needlessly bloating git-gui with git.git's history.

Thanks to Denton Liu <liu.denton@gmail.com> for providing me with a
script to generate and merge all the branches that were missing, which
made this task much easier.
