Subject: [PATCH 1/4 (alternate)] Add '--fixed-strings' option to "git log --grep" and friends

From: Jakub Narebski <[email-masked]>
Date: Wed, 27 Feb 2008 10:20:21 +0100

Add support for '--fixed-strings' option to "git log --grep"
and friends: "git log --author", "git log --committer".
Code is based on implementation of this option in "git grep".
