Hey everyone, I've attached (and pasted below) a couple of possible patches that fix FS#36097 (Wrong exit code for `pacman -Sg`).

The second patch seems a bit more sane to me in terms of the functionality. It just marks there to be a group found if the user didn't search for a specific group, regardless of whether any groups were actually found. I think this makes sense because in the highly unlikely scenario that there are no groups and the user didn't search for any specifically, pacman has still done everything it should have done so shouldn't return an error.
