#34 Fixes for pychecker2/main.py

[Kenneth J. Pronovici]

This patch came to me via Debian bug #453092 (http://bugs.debian.org/453092).

The SPE (Stani's Python Editor) folks have made some minor improvements to pychecker2/main.py, to make it handle errors better and make it more flexible.

I have integrated these changes into the Debian pychecker package. I would like to see them pushed into upstream CVS so I don't need to maintain a diff.

The changes are straightforward and look safe to me, and since SPE is already using them this implies that they work properly.

This patch is still a part of the Debian package, and no Debian bugs have been reported against the related functionality. I think that this implies that the changes are stable. I would like to see it applied to an upstream release if possible.
