Ah, is that it?  It seems strange indeed to have a command which does two
disjoint things (first move point then split the line) rather than just
splitting the line at point.

I typically don't want to type further on the old line after C-M-o.  If I
did, I would expect to type the space myself, or alternatively first move
point to after the space before typing C-M-o.

Maybe I should make my own private version of split-line.
