New submission from Rémi Rampin:
warnings._processoptions is called very early, before site-packages are
enabled. Because of this, using a non-standard 'category' will almost certainly
fail with the message:
Invalid -W option ignored: invalid module name: '...'
The -W option would be a lot more useful if it could actually match
non-standard categories (it does, after all, pretend to support
modulename.classname).
I don't see any easy way of fixing this, other than initializing the warnings
module later or matching category names with the given string (and getting rid
of the import).
