4507 * - When the matched pattern contains a line break, the old line
|
|
|
4508 * is taken from the line at the end of the pattern. The lines
|

4509 * in the match are deleted later, "sub_firstlnum" is adjusted

|

4512 * The new text is built up in new_start[]. It has some extra

4513 * room to avoid using alloc()/free() too often. new_start_len is
