Committing patch from Albert Ting on Zope maillist 4/12.  Regex change which fixes a table parsing problem.

from ExtensionClass, and reminded me that the 2.1 version of isinstance()

Upload buttons on DTML, Py Scripts, Files, Images and PTs raise an error
if the file is not specified instead of clearing the source (Bug #144)

the object pointers aren't initialized (because the constructor was called
with an invalid number of arguments)  This just amounts to using the XDECREF
macro rather than DECREF.
