tweaks: reshuffle the undo types into mostly the same order everywhere

Browse Source 
First the two that add something (ADD, ENTER), then the three that
delete something (BACK, DEL, JOIN), and then the one that changes
something (REPLACE).  Then the SPLITs, CUT, PASTE, and INSERT, and
then the INDENTs and COMMENTs, when they exist.
