[Yum] proxy

[Michael Rice]

proxy must be ftp or http[s] URL: _none_

Hey guys, the line above is new with an update from 2.2.0 to 2.4.0
(CentOS 4.2 -- sorry if this turns out to be their problem).

My repo file has proxy=_none_ after every repository definition, and I'm
getting the line above (same thing if I set it globally).  I can see
it's coming from the urlparse method and object, but it looks like it
shouldn't be passed at all .... the repos.py looks like it checks that
_none_ is a valid value, but I'm missing where it may set proxy to None
upon reading _none_.

Help! and thanks
