Note that this currently affects certain subnets where http_proxy is a
requirement. 

However, I'm running an internal private mirror.  I have $no_proxy set
to .cisco.com.  When the default Fedora config for [fedora] tries to get
the mirrorlist, a .cisco.com host is listed first.  In order to retrieve
the mirrorlist, I had to use the HTTP proxy, but the first host returned
needs to bypass the proxy.  Since no_proxy is broken, I need a
workaround.

I was thinking that I could replace the mirrorlist URLs with baseurl
pointing straight to my internal mirror and set proxy=_none_.  For repos
where I don't mirror internally, the yum.conf http_proxy would work
properly.

It appears your plugin removes http_proxy from env, but then yum.conf
http_proxy would be read and proxy=_none_ could override on a per-repo
basis.  I believe this provides the workaround I need, but it's not
ideal.

Thanks.
