Good question.

Yes, option `extended-command-suggest-shorter' controls
this.

Why this wasn't rolled into option `suggest-key-bindings'
(e.g. as another possible setting) I don't know.

Emacs didn't used to provide the `M-x some-abbreviation'
information.  That was added a release or two ago.  The
behavior was what you get if you customize option
`extended-command-suggest-shorter' to nil.
