Re: [PATCH] %default keyword expansion

Why not let Python do the work?  Instead of "%default", use
"%(default)s", and do this:

     def _expand_default (self, help_text, default):
         return help_text % {'default': default}

This mechanism could easily be expanded in the future to other
parameters.  It also allows for flexible formatting (e.g.,
"%(default).2f" with a float default).

Perhaps %prog should be redefined (or, additionally defined) in
this way also.
