Depends. Some packages will accept upper or lower case according to
the web site.

Curl only accepts lower case for http_proxy but accepts upper or lower
case for HTTPS_PROXY. That inconsistancy is probably because of this
bug. So this bug won't be a problem for somebody who uses PyCURL to
grab a remote url.

But for others???
