@@ -738,7 +738,9 @@ The three flag files `dirty`, `mark` and `scroll` read `0` or `1` and take an undo point (writing `1` pushes one now), and whether a write scrolls the pane. The writes of one open of `data`, `xdata` or `body` are one undo step while `mark` is 1 (so `printf 'a\nb\n' > data` is one, though a -shell writes it a line at a time), and the next open starts another; to +shell writes it a line at a time), and the next open starts another. The +pane has one history, so two opens writing at once take turns in it: each +open's first write after the other's starts a step of its own; to make a loop's writes one step, write `1` (an undo point here), then `0`, the writes, then `1` again. |
