bug#12190: 24.1.50; Minibuffer completion

[Dani Moncayo]

From "emacs -Q", type:
  M-x re-bu TAB TAB

I see that the first TAB produces "re-builder", and the second one says
that this is the sole completion.

The command I was looking for is `revert-buffer'.  I think it should be
reachable via completion in this case, i.e., starting with "re-bu".

That's expected: the default completion-styles starts with `basic' which
performs old-style prefix-completion, so the partial-completion does not
kick in.  Either add a * after `re', or change `completion-styles' by
removing `basic' from it.
