Did you "git clone" from your local repo or from the remote savannah
address?  The former should be very fast.

(or maybe it's an optional behavior that you need to activate with
some switch, see the documentation).

Every VCS has its downsides.  Bzr had only separate branches
(co-located branches were initially implemented in the last version);
git has only co-located branches.  You need to work around that.
