| 4643 * | |
| 1499 | 4644 * lnum The line number where we found the start of |
| 4645 * the match. Can be below the line we searched | |
| 4646 * when there is a \n before a \zs in the | |
| 4647 * pattern. | |

| 4651 * line breaks. | |
| 4652 * | |
| 4653 * Special situations: | |
| 4654 * - When the substitute string contains a line break, the part up | |
| 4655 * to the line break is inserted in the text, but the copy of | |
| 4656 * the original line is kept. "sub_firstlnum" is adjusted for | |
| 4657 * the inserted lines. | |
| 4658 * - When the matched pattern contains a line break, the old line | |
| 4659 * is taken from the line at the end of the pattern. The lines | |
| 4660 * in the match are deleted later, "sub_firstlnum" is adjusted | |
| 4661 * accordingly. | |
| 4662 * | |
| 4663 * The new text is built up in new_start[]. It has some extra | |
| 4664 * room to avoid using alloc()/free() too often. new_start_len is | |
| 1389 | 4665 * the length of the allocated memory at new_start. |
| 7 | 4666 * |
| 4667 * Make a copy of the old line, so it won't be taken away when | |
