[PATCH 1/9] grep: use get_pathspec() correctly

[Junio C Hamano <gitster@pobox.com>]

When there is no remaining string in argv, get_pathspec(prefix, argv)
will return a two-element array that has prefix as the first element,
so there is no need to re-roll that logic in the code that uses
get_pathspec().
