Subject: bug#9607: incorrect behavior with "auto-hscroll-mode nil" in ncurses/vt220 text operation; wrong in 23 but ok in 22.1
Date: Tue, 27 Sep 2011 00:01:50 -0400 [thread overview]
Message-ID: <gg7h4u8wgh.fsf@fencepost.gnu.org> (raw)
In-Reply-To: <6.2.5.6.2.20110926224200.05af3bc0@flumedata.com> (David Lawless's message of "Mon, 26 Sep 2011 22:43:50 -0400")
Present in 23.2 to 24.0.90 inclusive. Recipe:
emacs -Q --eval '(setq auto-hscroll-mode nil)'
Evaluate:
(dotimes (j 5)
(insert "\n")
(dotimes (i 10)
(insert "0123456890 ")))
Put point at start of first line of digits.
M-x scroll-left RET y
;; Window now scrolled to right-hand end of lines
Down arrow ; first time is ok
Down arrow
-> second time window scrolls back to left-hand end of line
(setq line-move-visual nil)
avoids the problem.
I guess it's related to the 2009-07 changes to line-move-visual for hscroll.
