  Indeed.  I've broken things up a little so that TAB-completion works.

  I did have some changes to RC_BIND to allow you to run:

    bind x alias_name

  Unfortunately that eventually causes problems, because SaveAction
 keeps pointers to my linked-list which get juggled around when aliases
 are added or removed.

  For the moment I've reverted that, which means I have to use this

    alias www screen -F -t www links
    bind W eval www

  That's not ideal, but I can live with it if I must.

  I suspect a similar issue is going to bite me if I allow aliases to
 be defined which point to other aliases.  This should be fine:

    alias blah echo  -> Allowed currently
    alias foo  blah  -> Not currently allowed, not hard to add.

   But anything that has pointers to saved arguments will be difficult.
