Patch 9.0.0167

[Bram Moolenaar]

Patch 9.0.0167
Problem: Checking for text properties could be a bit more efficient.
Solution: Return early when there are no text properties. Update TODO
items.
Files: src/textprop.c

* Text properties implementation. See ":help text-properties".
*
* TODO:
- * - Checking the text length to detect text properties is slow. Use a flag in
- * the index, like DB_MARKED?
* - Also test line2byte() with many lines, so that ml_updatechunk() is taken
* into account.
- * - Perhaps have a window-local option to disable highlighting from text
- * properties?
