git-gui: Don't attempt to tag new file/deleted file headers in diffs.

We don't want to tag these new file/delete file lines, as they aren't
actually that interesting.  Its quite clear from the diff itself that
the file is a new file or is a deleted file (as the entire thing will
appear in the diff).
