4510 * previous match or one further.

4512 * Mostly equal to matchcol, except for the first

|
|
4513 * match and after skipping an empty match.
|

|
4515 * new_start The new text, all that has been produced so
|
|
|
4516 * far.
|
|
|
4517 * new_end The new text, where to append new text.
|
|
|
4518 *
|
|
1499
|
4519 * lnum The line number where we found the start of
|
|
|
4520 * the match. Can be below the line we searched
|
|
|
4521 * when there is a \n before a \zs in the

|

4530 * to the line break is inserted in the text, but the copy of
|
|
|
4531 * the original line is kept. "sub_firstlnum" is adjusted for
|
|
|
4532 * the inserted lines.
|
|
|
4533 * - When the matched pattern contains a line break, the old line
|
|
|
4534 * is taken from the line at the end of the pattern. The lines
|
|
|
4535 * in the match are deleted later, "sub_firstlnum" is adjusted
|
|
|
4536 * accordingly.
|
|
|
4537 *
|
|
|
4538 * The new text is built up in new_start[]. It has some extra
|
|
|
4539 * room to avoid using alloc()/free() too often. new_start_len is
|
|
1389
|
4540 * the length of the allocated memory at new_start.
