Summary: parser cannot handle a comment containing a double dash

Initial Comment:
when attempting to parse a comment containing a double dash, the parser throws an exception stating that the double dash is not well formed:

import xml.parsers.expat
p = xml.parsers.expat.ParserCreate()
p.Parse('<!-- -- -->')

Traceback (most recent call last):
  File "test-expat.py", line 3, in ?
    p.Parse('<!-- -- -->')
xml.parsers.expat.ExpatError: not well-formed (invalid token): line 1, column 7

I'm using version 1.1, which shipped with python 2.4

This is not allowed - Expat is correct.
