[ELPA Syncer]

branch: elpa/paredit
commit 014cdfea76267e57daafac82dff1103e5e34b753
Author: Taylor R Campbell <campbell@mumble.net>
Commit: Taylor R Campbell <campbell@mumble.net>

    Handle shift selection in motion commands in recent GNU Emacs.
    
    Drop `backward-down-list'.  All four {backward, forward} x {up, down}
    motion commands are done pareditishly now.
