2243 Recording stack for undo:
2244 The following is an implementation of a compressed stack. Identical
2245 pushes are recorded by a negative prefix indicating the number of times the
2246 same char was pushed. This saves space for repeated curs-left or curs-right
2263 If the stack long int is 0-255 it represents a normal insert (from a backspace),
2264 256-512 is an insert ahead (from a delete), If it is betwen 600 and 700 it is one
2265 of the cursor functions #define'd in edit-impl.h. 1000 through 700'000'000 is to
2266 set edit->mark1 position. 700'000'000 through 1400'000'000 is to set edit->mark2
2269 The only way the cursor moves or the buffer is changed is through the routines:
2270 insert, backspace, insert_ahead, delete, and cursor_move.
2271 These record the reverse undo movements onto the stack each time they are
2274 Each key press results in a set of actions (insert; delete ...). So each time
2275 a key is pressed the current position of start_display is pushed as
2276 KEY_PRESS + start_display. Then for undoing, we pop until we get to a number
2277 over KEY_PRESS. We then assign this number less KEY_PRESS to start_display. So undo
2278 tracks scrolling and key actions exactly. (KEY_PRESS is about (2^31) * (2/3) = 1400'000'000)
