I'll make it so that the prefix arg is passed on in the cycle so M--
M-SPC M-SPC will delete all space including newline before point. IMO,
that's better than a separate action.

Yes, in the sense that negative means "including newlines".

Right now and with my patch, M-- M-SPC would call (just-one-space -1)
and the next M-SPC would start another cycle with (just-one-space 1)
because the prefix arg changed.
My suggestion is that M-- M-SPC M-SPC will call (just-one-space -1)
(delete-space-before -1) [ok, the latter is no function but you get the
idea].
