minor nit: I think we could drop the redirection as grep can take the
file name as an argument.

I'm not sure if there's a grep out there that prints the filename before
the count even if it deals with a single file.  git grep does that, at
least.  POSIX[3] implies the lack of filename prefix for the single file
case, but I don't know if we can rely on that everywhere.

Except we got plenty of "grep -c" calls with a single filename and no
redirection in t/ already.  Adding one more should be fine.
