I made three small patches for lisp/mpc.el.
1.
I noticed M-x mpc-playlist-delete always messages “Deleted 1 songs”
even if playlist queue has more than one songs.
This is because mpc-cmd-delete’s sort modifies songs-poss by side
effect. Using copy-sequence fixes this. (also fix mpc-cmd-move for
same reason)

M-x mpc-songs-jump-to doesn’t update *MPC-Status* buffer.
Use mpc-cmd-play.

M-x mpc-stop clears playlist queue. So updating *MPC-Songs* buffer
is useful.

Please review these patches.
Do I have to squash these patches to one commit?
