Re: interesting question about shells
Bash and Zsh will already handle your first example without any tinkering. As Christian stated the completion systems are quite mature, I tend to prefer zsh myself. A good book that I recommend to get started is From Bash to Zsh. I found it easier to start with rather the supplied reference documentation.

It sounds like a great book idea, but it looks to me like the book literally just covers Bash and Zsh? Is that the case?
Re: interesting question about shells
No really.. a lot of the basics are applicable to ksh (*sh) but *csh style shells aren't covered.
