PyChecker

Yup, I never updated pychecker much to handle generator expressions. Let
me know if you find more problems. This one is fixed:

I also hit this bug:

self._include_labels = frozenset(label.lower() for label in
include_labels)
self._exclude_labels = frozenset(label.lower() for label in
exclude_labels)

demetrius/googleprojectlist.py:42: Redefining attribute (<generator
expression>) original line (41)

This seems to be basically the same problem as reported in Debian bug
#408261:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=408261

That bug report uses the following code:

def main():
' '.join(str(x) for x in range(10))
' '.join(str(x) for x in range(11))

It gets a similar result:
