Oh you have not tested this at all, have you?

You're missing ;; at the end of the case, this is not correct bash
syntax and completely breaks the script.

When you respin please use spaces instead of tabs (I know, *very*
annoying but that's apparently how things should be for bash
completions :/).

And please add "tree" to the *) case which completes the actions.
