Re: [PATCH] grep: provide pathspecs/patterns via file or stdin

Teach 'git grep' how to receive pathspecs via file, and add convenience
flags for receiving pathspecs or patterns via stdin.

When I invented the terms "pathspec", "refspec", etc. for this
project, I meant them to be collective nouns.  A pathspec is a set
of pathspec elements, each of which is usually given as a separate
argument on the command line.  So "Read pathspec from file" is good
(not "Read pathspecs from file").

Are you aware of the am/pathspec-from-file topic that has been
cooking for a while by now?

I do not necessarily agree with the second rationale why many
commands may want to learn this option given in that series, but do
agree with the first one.  A lot of times running underlying "git"
command multiple times via xargs invocation can mean quite different
thing from giving a large pathspec to a single invocation of "git".
But not with "git grep" ;-)  So I'd say this is a second class
target for the pathspec-from-file theme.

Thanks.
