I'm sure it's simple once you understand it, but looking at wiki.py
it's pretty easy to get lost on what is actually happening.  This has
got to be one of the best candidates for being rewritten with the re.X
option I've ever seen:

word_rule =3D=20
ur'(?:(?<![%(l)s])|^)%(parent)s(?:%(subpages)s(?:[%(u)s][%(l)s]+){2,})+(?![=
%(u)s%(l)s]+)'
% {
'u': config.chars_upper,
'l': config.chars_lower,
'subpages': config.allow_subpages and (wikiutil.CHILD_PREFIX + '?') or '',
'parent': config.allow_subpages and (ur'(?:%s)?' %
re.escape(PARENT_PREFIX)) or '',
}

And I thought I knew reg expressions pretty well!

Thanks for everyone's help so far... I'm still chugging at it...
