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.

I can reproduce this in Emacs 24.4, but not in Emacs 25.1 nor the latest pretest of Emacs 26.2. Your Emacs version is quite old, so I suggest to try a newer one (the last released version is 26.1, and 26.2 is going to be released soon), as it seems that this was a problem in that old version that was already fixed. Thanks.
