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. -- Alan Mackenzie (Nuremberg, Germany).
