Indeed, so it's not a good choice either.

Yes and no: it typically isn't recognized as C-SPC but as C-@ (aka ASCII
NUL).  Luckily (well it's actually done on purpose) C-@ has the
same binding, so it does DTRT.

In contrast on most tty C-return just sends a RET and we can't put that
special binding on RET as well.

I'm not saying C-return can't be used, but it would be good to also find
a key that works on ttys (just like we have undo bound to C-x u for "works
everywhere" as well as to C-_ and C-/ for more convenient alternatives
that don't always work).  Maybe we could just use C-x r (except it would
hide the register commands ;-( ).

Hmmm... OK.  I was thinking it would be good to make it work like a general
prefix command so you could also do C-return M-C-SPC, but after thinking
about it, I see it's not that important as long as M-C-SPC C-return works
as well.

Good.  I assume it only works if you use transient-mark-mode, otherwise it
has no way to know whether you're "in the middle of marking" or not.

Fine with me, C-return is no worse than S-return.
