| 4625 * previous match or one further. | |
| 4626 * prev_matchcol Column just after the previous match (if any). | |
| 4627 * Mostly equal to matchcol, except for the first | |
| 4628 * match and after skipping an empty match. | |

| 4631 * far. | |
| 4632 * new_end The new text, where to append new text. | |
| 4633 * | |
| 1499 | 4634 * lnum The line number where we found the start of |
| 4635 * the match. Can be below the line we searched | |
| 4636 * when there is a \n before a \zs in the | |
| 4637 * pattern. | |

| 4646 * the original line is kept. "sub_firstlnum" is adjusted for | |

| 4649 * is taken from the line at the end of the pattern. The lines | |
| 4650 * in the match are deleted later, "sub_firstlnum" is adjusted | |
| 4651 * accordingly. | |
| 4652 * | |
| 4653 * The new text is built up in new_start[]. It has some extra | |
| 4654 * room to avoid using alloc()/free() too often. new_start_len is | |
| 1389 | 4655 * the length of the allocated memory at new_start. |
