| 4676 * match and after skipping an empty match. | |

| 4679 * far. | |
| 4680 * new_end The new text, where to append new text. | |
| 4681 * | |
| 1499 | 4682 * lnum The line number where we found the start of |
| 4683 * the match. Can be below the line we searched | |
| 4684 * when there is a \n before a \zs in the | |
| 4685 * pattern. | |

| 4697 * is taken from the line at the end of the pattern. The lines | |
| 4698 * in the match are deleted later, "sub_firstlnum" is adjusted | |
| 4699 * accordingly. | |
