C-RET doesn't sound like a good choice to me, both because it's
counter-intuitive (I expect C-RET to "terminate" something like RET
terminates a line or terminates minibuffer input), and because it's not
available in xterms (which also can't use M-TAB).

I agree that Emacs should choose a binding for it.

Personally, I've been using TAB for that purpose.  It's convenient and
natural since TAB is already used for completion in many other contexts,
but it's also kind of tricky since TAB is also used for indentation.
I resolve this problem by first trying indentation and if indentation
did not do anything, then I try completion.  It works for me, but I'm
not that thrilled about it.
