Comment 5 for bug 168050

Originator: NO

I already modified the launcher code to escape several other problematic
characters, and ran into one case I couldn't fix due to OSX's use of
directory seperators (see
http://sourceforge.net/tracker/?func=detail&aid=1653742&group_id=93438&atid=604306).

We can try just escaping these characters, but maybe we need to coe up
with a more general fix for this problem.
