Why would you put -n in $EDITOR? This is mostly used by programs that 
want to invoke an editor on a temp file and then do something when 
you're done editing it, such as "crontab -e", "vipw", or readline's C-x 
C-e.  So it should always be set to a command that waits.

Maybe you're trying to deal with Emacs deadlocking if you use one of 
these commands from M-! inside Emacs? The solution in this case is to 
background the command with &.
