| 4554 * previous match or one further. | |
| 4555 * prev_matchcol Column just after the previous match (if any). | |
| 4556 * Mostly equal to matchcol, except for the first | |
| 4557 * match and after skipping an empty match. | |

| 4560 * far. | |
| 4561 * new_end The new text, where to append new text. | |
| 4562 * | |
| 1499 | 4563 * lnum The line number where we found the start of |
| 4564 * the match. Can be below the line we searched | |
| 4565 * when there is a \n before a \zs in the | |
| 4566 * pattern. | |

| 4578 * is taken from the line at the end of the pattern. The lines | |
| 4579 * in the match are deleted later, "sub_firstlnum" is adjusted | |
| 4580 * accordingly. | |
