I am not sure of that. I thought there was interest in full-tree grep
(OK, _I_ had some interst in it).  But the same transition pain
arguments apply there, and we should be able to do "git grep pattern :/"
soon, right?

I never tested it myself, but the earlier "support :/ at a wrong level
get_pathspec()" patch should take care of "git grep" as well.  It is
equivalent to the "alternative approach" Michael posted as RFC as a
follow-up to his earlier "grep --full-tree" thread.
