yum has problems with proxy

[Mikus Grinbergs]

On my XO, I am a heavy user of yum.  The communications setup at my 
home goes through a proxy to reach the internet.  I have empirically 
seen that when told to go from the XO to the net through a proxy, 
'opera' handles "https:" URLs correctly, whereas 'yum' does not.

Package 'fedora-release-10.92' (included in rawhide-xo) set up one 
yum control file ('fedora-rawhide.repo') with "https:" URLs.  I had 
to go into that file and manually change those URLs to "http:" in 
order for my XO to be able to use yum from home.  Now the upcoming 
package 'fedora-release-11' sets up __all__ the yum control files 
with "https:" URLs -- I now had to modify four .repo files to be 
able to use yum in f11 on the XO when I'm at home.
