| 4720 * far. | |
| 4721 * new_end The new text, where to append new text. | |

| 4724 * the match. Can be below the line we searched | |
| 4725 * when there is a \n before a \zs in the | |
| 4726 * pattern. | |

| 4736 * the inserted lines. | |
| 4737 * - When the matched pattern contains a line break, the old line | |
| 4738 * is taken from the line at the end of the pattern. The lines | |
| 4739 * in the match are deleted later, "sub_firstlnum" is adjusted | |
| 4740 * accordingly. | |
| 4741 * | |
| 4742 * The new text is built up in new_start[]. It has some extra | |
| 4743 * room to avoid using alloc()/free() too often. new_start_len is | |
| 1389 | 4744 * the length of the allocated memory at new_start. |
