Try this:

  (define-alternatives web)
  (setq web-alternatives '(("eww" . eww)))
  M-x web RET TAB RET

Does not work without the attached patch.

I think it's safe to recommend `define-alternatives' for commands
only, not for function, and the docstring suggests this too.  If so,
I'll apply the patch.

Two other problems:

1) when there is only one "alternative", the user is asked which
   one he wants.  I think COMMAND should use the alternative without
   asking, and tell the user how to add other alternatives through
   COMMAND-alternatives for 2 secs the first time the alternative is

2) Once an alternative is chosen, setting COMMAND-alternatives will
   not take any effect, and I don't see a way to cancel the first

What do you think?
