git rev-list --author/--committer b0rked with -F/--fixed-strings

Hello all,

I was recently looking into the reason why the gitweb search box
failed to provide results when using the author and committer
search and NOT using regexp searches.

I managed to track the fault down to the inability for git
rev-list to handle --author and --committer in conjunction with
the --fixed-strings option.

It's not difficult to see that the reason for this is that the
author and committer search patterns are *always* built as regular
expressions. However, I couldn't see any obvious way to do things
in a *different* way ...

So, is this a known bug (I would call it a bug, yes) in rev-list?
Are there any ideas around on how to fix it?
