[arch-general] Belated Arch-Conf pacman improvement suggestion

[Greg Minshall]

thanks everybody for the conference!  in addition to the content (and
getting to see at least a few people's faces), the production details
were great.

something like this would be nice (where the "marking" would survive for
"this run" of pacman, and maybe really means, "move to the end of the
list of mirrors to try").

cheers, Greg
