I think there are two patches available to do the same thing - sorry for 
not following up on this sooner. I brought this up in conversation with 
Bill on this list back in October and haven't dug into it since.

I attached the patch to a bug opened by Cameron Stokes

I agree that this functionality would be nice to have but am agnostic as 
to which method accomplishes this :) They both seem to take different 
routes to get to the same goal.

Jim, if you wouldn't mind reviewing both and suggesting one to be 
cleaned up for a patch generated against trunk. I'm happy to volunteer 
the effort to adjust my patch or at least take care of that bug that's 
out there still.
