The git repository was only used before we switched to bzr.  To my
knowledge, it has not been used since.

This is a bug in the Savannah hosting service, not in bzr.  A fix for it
appears to be in progress:

Until this is fixed, if you have difficulty with the download size of
updates, you can use the bzr mirror on Launchpad, which is updated
several times a day:
  bzr get lp:grub/grub2

It would if git were artificially limited to an inferior transport
mechanism the way that bzr currently is on Savannah.  Right now, you are
not comparing like with like.  With sftp, bzr basically ends up forced
to redownload much of the branch metadata for every operation; it can do
much, much better with bzr+ssh.
