Eek!  I'd rather shove this into a new layer below specfile/template
expansion, which would do something like that:

   s/\$Date:.*\$/$Format:$$Date: %aD$/

This way A) the complexity and ugliness affects only the users of these
fields, while $Format:...$ users are not adversely affected, and B) we
can first implement $Format:...$ handling and add the rest later.

In order to expand $Id$, git-archive would need to run some kind of
callback, right? :-/  Let's first see if such a thing is really needed.
