Commands like wemux pair should exit with a non-zero status when the command
fails. In my specific use case, .bash_profile attempts to attach to wemux, if
running, and falls back to a different command if not running.
$ wemux pair
No wemux server to pair with on 'wemux'.
$ echo $?
I believe this patch covers all the client commands. I haven't looked at the
server commands, so you may want to do that own your own.
Return an error exit status from client commands that fail
Makes good sense, thank you! Sorry for the insane delay.
