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.

Basic install:

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help
