There *are* people who import sre or pre because they think they have
a preference.  I propose to lose PCRE, but keep sre and pre as
(deprecated) aliases for re.  I.e. e.g.

    # pre.py
    import warning as _warning
    _warning.warn(..., "please use re, not pre")
    from re import *

And ditto for sre.  (Except maybe sre is an implementation artefact that
may be harder to get rid of -- I'm not in a hurry there.)
