    patch 9.0.0167: checking for text properties could be a bit more efficient

    Problem:    Checking for text properties could be a bit more efficient.
    Solution:   Return early when there are no text properties.  Update TODO
                items.

- * - Checking the text length to detect text properties is slow.  Use a flag in

  * - Also test line2byte() with many lines, so that ml_updatechunk() is taken

- * - Perhaps have a window-local option to disable highlighting from text
- *   properties?
