-It is possible to run a completion on a string with spaces in it, e.g., `z us bi<TAB>` might take you to `/usr/local/bin`. This works, but as things stand, after the completion the command line reads

-You get where you want to go, but the detritus on the command line is annoying. This is also a problem in `rupa/z`, but I am keen on eventually eliminating this glitch. Advice is welcome.
