Speed up hg grep by avoiding useless manifest parsing

In the kernel repo (tip = 2b89f7111b96), a "hg grep mpm MAINTAINERS" goes
from ~165s to 0.7s.  This could get even a bit faster if we broke out of
the loop after the first match, but I'm not sure how that would interact
with the --follow code.

This is obviously an extreme example, but other cases should also benefit
from this patch.
