Also also. I was a little turned off by the fact that every fetch is
going to do the equivalent of "git log --raw -m $new --not $old",
whether you have submodules or not.

Notice I called your patch solving "the other half"?
See http://thread.gmane.org/gmane.comp.version-control.git/181101

Oh, heh. I totally missed that thread. I don't usually pay attention to
submodule patches, and came at this completely from the "why is git
fetch so slow" angle. Glad to see Jens and I are meeting in the middle.
