4674 * needs to be copied to the new text. | |
4675 * matchcol Column number of the old text where to look | |
4676 * for the next match. It's just after the | |
4677 * previous match or one further. | |
4678 * prev_matchcol Column just after the previous match (if any). | |
4679 * Mostly equal to matchcol, except for the first | |
4680 * match and after skipping an empty match. | |
4681 * regmatch.*pos Where the pattern matched in the old text. | |
4682 * new_start The new text, all that has been produced so | |
4683 * far. | |
4684 * new_end The new text, where to append new text. | |
4685 * | |
1499 | 4686 * lnum The line number where we found the start of |
4687 * the match. Can be below the line we searched | |
4688 * when there is a \n before a \zs in the | |
4689 * pattern. | |
7 | 4690 * sub_firstlnum The line number in the buffer where to look |

4692 * when the pattern or substitute string contains | |
4693 * line breaks. | |
4694 * | |

4696 * - When the substitute string contains a line break, the part up | |
4697 * to the line break is inserted in the text, but the copy of | |
4698 * the original line is kept. "sub_firstlnum" is adjusted for | |
4699 * the inserted lines. | |
4700 * - When the matched pattern contains a line break, the old line | |
4701 * is taken from the line at the end of the pattern. The lines | |
4702 * in the match are deleted later, "sub_firstlnum" is adjusted | |
4703 * accordingly. | |
4704 * | |
4705 * The new text is built up in new_start[]. It has some extra | |
4706 * room to avoid using alloc()/free() too often. new_start_len is | |
1389 | 4707 * the length of the allocated memory at new_start. |
7 | 4708 * |
