I think the newline-including variations would be as popular as the
non-newline ones, so I think we should have those variations for all of
the actions.

Perhaps `M--' could work as a toggle -- if the action doesn't include
newlines, `M--' switches on, and if it does, `M--' switches it off.

But it doesn't have to be, surely?  No prefix for
delete-space-after-point could mean exactly that, but a prefix of four
could mean leave four.
