4641 * far. | |
4642 * new_end The new text, where to append new text. | |
4643 * | |
1499 | 4644 * lnum The line number where we found the start of |
4645 * the match. Can be below the line we searched | |
4646 * when there is a \n before a \zs in the | |
4647 * pattern. | |

4650 * when the pattern or substitute string contains | |
4651 * line breaks. | |

4659 * is taken from the line at the end of the pattern. The lines | |
4660 * in the match are deleted later, "sub_firstlnum" is adjusted | |
4661 * accordingly. | |

4664 * room to avoid using alloc()/free() too often. new_start_len is | |
