grep: invoke the file prefetch hook
Because of the way `grep` works, I don't see an easy way to prefetch everything,
so this prefetches per revision as it walks. The message between the file/line
number and the matching line is a --verbose output. Since I don't expect this
to be used much with lfs content, I'm not going to worry about it.
I have no idea why the second test without an explicit file doesn't find the
match.
