It looks ok.  It would look different on Savannah.
http://git.savannah.gnu.org/cgit/emacs.git

Note that since your git clone I've created two branches
(invoke, plus callcc, which is branched off invoke).
That might change things.

It depends on the goal.  If the goal is to switch over to git as the
primary repository, then the mirroring doesn't have to be full.
In fact we don't *need* automatic mirroring at all - its just nice.

At the very list we need to git repository on Savannah.  It doesn't
have to be a mirror of the svn repository, though that would be nice.
It's acceptable for it to just be a static snapshot, or one that can
be manually brought up to date - only needed during the evaluation period.

If after the evaluation period we decide to make the switch, then we
freeze the old repository (easy as long as I'm the only committer).
Then we do a final update from the old repository, and then after
some testing we declare the new repository as the primary one.

Of course if bi-directional mirroring is easy to set up, I won't
say no :-)
