The following is an annoying behavior of GNU emacs (at least in 18.53
BSD 4.3, on a Vax):

Create three files: "foo", "foo1", and "foo-2".

Now do ``C-x f foo''
Hitting <tab> gives the message "[Complete, but not unique]" this
implies that there is a file called "foo".
Hitting <space> extends "foo" to "foo-" at which point either <space>
or <tab> completes this to "foo-2".

The problem is that "foo" and "foo-2" can be reached as completions of
"foo" but "foo1" can't be reached.  It seems like the "[Complete, but
not unique]" message should really cause a completion buffer to appear
as well.
