5048 * previous match or one further. | |
5049 * prev_matchcol Column just after the previous match (if any). | |

5054 * far. | |
5055 * new_end The new text, where to append new text. | |
5056 * | |
1499 | 5057 * lnum The line number where we found the start of |
5058 * the match. Can be below the line we searched | |
5059 * when there is a \n before a \zs in the | |
5060 * pattern. | |
7 | 5061 * sub_firstlnum The line number in the buffer where to look |

5063 * when the pattern or substitute string contains | |
5064 * line breaks. | |
5065 * | |

5072 * is taken from the line at the end of the pattern. The lines | |
5073 * in the match are deleted later, "sub_firstlnum" is adjusted | |
5074 * accordingly. | |
5075 * | |
5076 * The new text is built up in new_start[]. It has some extra | |
5077 * room to avoid using alloc()/free() too often. new_start_len is | |
1389 | 5078 * the length of the allocated memory at new_start. |
