|
|
* new_end The new text, where to append new text.
|
|
*
|
|
* lnum The line number where we found the start of

|
|
* when there is a \n before a \zs in the
|
|
* pattern.

|

* line breaks.

|

* accordingly.
|

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

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

|
* the length of the allocated memory at new_start.
|
