This is probably one of the remaining 2% of cases ;) But I do not see
much sense in such a configuration. Saying for the http:// schema: "when
$http_proxy is set and host does not match a $no_proxy entry, then use
$http_proxy. Else, use direct connections" is the normal case, and is
*not* supported by yum/urllib.

This method works well on CLI tools (wget, curl) and browsers (w3m,
lynx, konqueror) which are specialized on WWW-access, and it can be set
globally (e.g. with a /etc/profile.d/ script). I do not know, why yum
would need a yet-another proxy-configuration.
