Ah, sharp eye!  I now have things the way I had it before, but in more
portable manner...

    alias b='cd ~-'
    _cd ()
    {
	local cur=${COMP_WORDS[$COMP_CWORD]}

	COMPREPLY=( $(compgen -W "`dirs`" -- $cur) )
    }
    cd () { pushd "${1:-$HOME}" ; }
    bind -m vi-insert -x '"\C-t": popd'	# <Ctrl-t>, just like Vi tags
    complete -o dirnames -F _cd cd
    complete -d popd pushd		# list only the directories.

<Ctrl-t> is bound to 'popd', so you can go back to previous directories,
much like when you work with tags in Vi.

Thanks.  'bind -x ...' was the key.
