I was reading the changes at python.org and came across
this tidbit:

One error that Python programmers occasionally make is writing the
following code:

except TypeError, ValueError: # Wrong!

The author is probably trying to catch both TypeError and ValueError
exceptions, but this code actually does something different: it will
catch TypeError and bind the resulting exception object to the local
name "ValueError". The ValueError exception will not be caught at all.
The correct code specifies a tuple of exceptions:

except (TypeError, ValueError):

Does this mean I'll need to go through the latest revision of
change-svn-wc-format.py and modify these exception catching
