4635 * far. | |
4636 * new_end The new text, where to append new text. | |
4637 * | |
1499 | 4638 * lnum The line number where we found the start of |
4639 * the match. Can be below the line we searched | |
4640 * when there is a \n before a \zs in the | |
4641 * pattern. | |

4644 * when the pattern or substitute string contains | |
4645 * line breaks. | |
4646 * | |

4653 * is taken from the line at the end of the pattern. The lines | |
4654 * in the match are deleted later, "sub_firstlnum" is adjusted | |
4655 * accordingly. | |

4658 * room to avoid using alloc()/free() too often. new_start_len is | |
1389 | 4659 * the length of the allocated memory at new_start. |
