looks like a bug in the new (2.0) engine:

>>> import pre # 1.5.2's regular expression engine
>>> p = pre.compile("x*")
>>> p.sub("-", "abxd")
'-a-b-d-'

>>> import sre # 2.0's regular expression engine
>>> p = sre.compile("x*")
>>> p.sub("-", "abxd")
'-a-b--d-'

I've added it to the sourceforge bug list (issue #462270)
