git-grep: fix 'git grep -e $pattern' handling

Junio C Hamano · Junio C Hamano · commit c9fc748f8485 · 2005-09-24T15:09:48.000-07:00
People typically say 'grep -e $pattern' because $pattern has a leading
dash which would be mistaken as a grep flag.  Make sure we pass -e in
front of $pattern when we invoke grep.
