I don't know where you got the impression that this would work, but it 
definitely won't.  Even if $EDITOR was previously unset, it'd set 
$EDITOR to "/usr/bin/emacs:" which is what programs will try to use as 
your editor.  There is no program /usr/bin/emacs: on my computer, and I 
doubt there's one on yours.  You're probably used to the $PATH variable, 
which is a colon-delimited string.  $EDITOR can only be the path to an 
executable.

If you expected to have it choose the default, and if it isn't provided, 
use emacs, what you probably mean is something like this:

export EDITOR=${EDITOR-/usr/bin/emacs}

(If I recall correctly, feel free to correct me)
