Well, the only thing we need to do in fetching between two
repositories that are already identical should be to compare
ls-remote output from both ends and immediately declare victory,
and it is unacceptable for such an obvious no-op to take 30
seconds.  At this point it really is the shell loop that is
killing us.

I've applied your fixes to jc/fetch topic and merged it back to
'pu'.  Thanks.
