[Zope-Checkins] CVS: Zope2 - UnTextIndex.py:1.33.2.16

[andreas@serenade.digicool.com]

Update of /cvs-repository/Zope2/lib/python/SearchIndex
In directory serenade:/tmp/cvs-serv18668

Modified Files:
      Tag: zope-2_3-branch
	UnTextIndex.py 
Log Message:
Fixed (hopefully) a longtime outstanding problem in parens():         
- the former regex never matched any parentheses
- the parens() used old regex module API although 're' module was used
