28.0.50; incorrect cursor position in visual-line-mode when word-wrap-by-category is t |
|
Date: |
Wed, 13 Jan 2021 10:27:24 +0800 |
Steps to reproduce:
1. emacs -Q
2. eval the following code in the *scratch* buffer:
(with-current-buffer-window "*test*" nil nil
(dotimes (_ 3)
(dotimes (i 10)
(insert "一二三四五六七八九十"))
(dotimes (i 20)
(insert "test ")))
(setq word-wrap-by-category t)
(visual-line-mode))
3. In the *test* buffer, C-a/C-e don't always move the cursor to the
beginning/end of screen line. There is also an offset between the mouse
click location and the cursor position. If there seems to be no problem,
you can adjust the window width and recheck the cursor movement.

Thanks for the feedback. I've now installed that change, and I'm
closing this bug.
