Subject: bug#23570: 25.1.50; Cursor motion error with visual-line-mode
Date: Wed, 18 May 2016 19:20:28 +0800 [thread overview]
Message-ID: <87lh374npf.fsf@gmail.com> (raw)
When visual-line mode is enabled, there is a bug causing the cursor to
fail to find the right start/end of a screen line. I see the bug with
Emacs 24.5, as well as the latest git version. No bug in Emacs 24.4.
1. emacs -Q
2. Insert the following (at the start of a new line):
123456789 123456789 123456789 123456789 123456789 123456789 123456789 12 ABCDEFGHIJK MOPQ
3. M-x visual-line-mode RET
4. Adjust the window width until it is just large enough for
"ABCDEFGHIJK" to be on the first line.
5. Decrease the window width by 1 character. Now, "ABCDEFGHIJK" should
be wrapped to the second line.
5. Move point to the beginning of the line starting with "1234...".
Now, typing C-e moves to the second screen line. Expected result: it
should move to the end of the first screen line.
Various other screen oddities are observable in the vicinity of this
wrapped line. For instance, when point is on "Q", C-a moves to the
space before "M", rather than the start of the line.
In GNU Emacs 25.1.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.20.3)
