Hmm, I was afraid this would be confusing/misleading :)
All my references to NoUpgrade don't refer to the static NoUpgrade definition
in /etc/pacman.conf , but the representation of it in pacman at runtime.

So pacman temporarily adds files a noupgrade list, so that remove_commit()
doesn't kill them. And when it's done, it removes them from the noupgrade
list.
It never edits the NoUpgrade files in pacman.conf.

The case I described is when a config file that was in the backup array
leaves the backup array, like what happened with /etc/pacman.d/current.
