[pacman-dev] [PATCH] Allow -c,--conf option for ABS

In creating my python arch integrity script, which looks for various issues in pkgbuilds and repos, I found it would be useful to be able to have both an abs.conf and an abs64.conf that I can call abs directly with. Right now I have to keep (un)commenting lines each time I want to update the abs tree for each arch, which is a pain. So here's a patch that allows the user to pass -c or --conf. I have no idea if I used git correctly, but it gave me a patch. Scott
