I guess this could be considered an RFC of sorts. For anyone out there
who doesn't know much about bugzilla, just visit
http://bugzilla.redhat.com and use the "Goto bug#" field at the top
right of the front page to visit these bugs. You can see the patches,
enter comments, and so forth. Most of these are small and simple.
