Summary: sub-tle difference between pre and sre

Initial Comment:
as reported by Carlos Gaston Alvarez on 
comp.lang.python (verified in 2.1.1 and 2.2a3):

>>> import pre
>>> p = pre.compile("x*")
>>> p.sub("-", "abxd")
'-a-b-d-'

>>> import sre
>>> p = sre.compile("x*")
>>> p.sub("-", "abxd")
'-a-b--d-'
