[Jeremy Hylton]

Update of /cvs-repository/Zope/lib/Components/ExtensionClass/src
In directory cvs.zope.org:/tmp/cvs-serv10078

Modified Files:
	ExtensionClass.c 
Log Message:
experimental change to help debugging: given decent repr to PMethod objects

It's experimental because I just called snprintf() directly, even
though later version of Python go through elaborate rituals before
calling it.
