I checked with Guido and he thinks the feature is "nifty" but 
that the language is cleaner and easier to maintain without 
it (especially since it would entail similar changes to the 
unicode and UserString modules).

Thank you for the suggestion.

Closing the request.

The optional character for center seems like a useful idea 
to me.  People occasionally like to center captions in fields 
of hyphens or asterisks.  Note, this proposal is similar to 
the recent "optional character" enhancements to str.strip
(), str.lstrip(), and str.rstrip().

Doing the same for zfill() is more problematic because 
both its name and function do not equate to "padleft".  
The 'z' in zfill implies that a zero will be used.  The actual 
function not only fills to the left, but also repositions any 
leading minus signs.
