So with this change, the help looks like:

$ bzr tags -h
Purpose: List tags.
Usage:   bzr tags

Options:
   --sort=ARG            Sort tags by different criteria.  "alpha": Sort 
tags
                         lexicographically (default).  "time": Sort tags
                         chronologically.
   -v, --verbose         Display more information.

Which is probably better than what we have.

I think we were hoping for something more like:
$ bzr tags -h
Purpose: List tags.
Usage:   bzr tags

Options:
   --sort=ARG            Sort tags by different criteria.
                           alpha   Sort tags lexicographically (default).
                           time    Sort tags chronologically.
   -v, --verbose         Display more information.

I realize this is probably not possible to do, because the optparse code
automatically re-wraps the help, and you would have to somehow get past 
all of
that.

So in the short term, I think this is better than what we have, so I'll 
approve
it.
