Bring up an editor for --description if it's not supplied

If there's no description, bring up an editor to allow the user to enter one. If they specify an editor to use, do that. Otherwise look for EDITOR in the environment and if all else fails default to vi if on UNIX (the most likely editor to be on any system).
