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