| 4653 * the original line is kept. "sub_firstlnum" is adjusted for | |
| 4654 * the inserted lines. | |
| 4655 * - When the matched pattern contains a line break, the old line | |
| 4656 * is taken from the line at the end of the pattern. The lines | |
| 4657 * in the match are deleted later, "sub_firstlnum" is adjusted | |
| 4658 * accordingly. | |
| 4659 * | |
| 4660 * The new text is built up in new_start[]. It has some extra | |
| 4661 * room to avoid using alloc()/free() too often. new_start_len is | |
| 1389 | 4662 * the length of the allocated memory at new_start. |
| 7 | 4663 * |
