[PyChecker-list] Proposed fix for "tuple index out of range" INTERNAL ERROR

[Dustin L. <qh...@gm...>]

Here is the use case and a fix for this error.  Let me know if there is a
more efficient way to present this.

groucho:~/projects/python/pychecker/pychecker-0.8.19
$ cat ../test_checkbuiltins.py
def foo_func():
    s = "foo"
    return '%s' % s.center(1)

groucho:~/projects/python/pychecker/pychecker-0.8.19
$ python pychecker/checker.py ../test_checkbuiltins.py
