From: A Kurn <kurn <at> sfu.ca> To: bug-gnu-emacs <at> gnu.org Subject: 24.4; scroll-up Date: Thu, 20 Dec 2018 19:00:15 -0800
--text follows this line-- When I scroll up, using scroll-up, and point is at the top of the screen, point moves so that the scroll can take place and still leave point on the screen. Point remains in the first line. OTOH, when I scroll down and point is on the last line, it jumps to the second-last line. This is an error and new behavior. It should be on the last line, mirroring the behavior of scroll-up. This is a minor bug, but it has upset some of my scripts. I've seen some really odd behavior also: In some situations, it actually unscrolls, canceling the scroll in order to keep point on the screen. I hope that fixing the first bug will fix this also, so I don't have to reproduce the problem for you. Fix please.
