Promoting a package in a pocket to main

[Michael Casadevall]

Relevant bug: https://bugs.edge.launchpad.net/ubuntu/+source/xfprint4/+bug/211335

Essentially xfprint4 should depend on a2ps, but that is impossible
since xfprint4 is in main (in gutsy, and dapper), and a2ps is in
universe. Talking with the LP admins, promotion within a pocket is
possible, but I'd believe this requires discussion before any actions
are taken.
