You probably mean this thread, which is (apparently) unrelated to the current bug: From: Warren L Dodge Subject: Re: C-a acts different in 22.0.90 then past versions To: storm@cua.dk (Kim F. Storm) Cc: emacs-pretest-bug@gnu.org, warren.l.dodge@tektronix.com I'll try emacs-22.0.96 as soon as I can get it built. In the mean time here is the answers to all the other questions. emacs-22.0.90 -Q c-xc-f /etc/termcap c-xc-q To make it writable c-kc-kc-y kill the first line and put it back. It will not do it without this line kill c-s the do this until you leave the first screen displayed. This will recenter the buffer on the "the" found. Then c-s for one more "the" below but on the same display screen. For the GNU/Linux on the redhat 4.0 release it was about 16 additional c-s commands to get it. I think near the bottom will work also. c-a this will recent the screen on the line where the "the" was at.

The problem shows up in 22.0.90, but is solved in 22.0.96. I believe this is a bug I fixed. I think the fix was in isearch.el, though that part of the memory is not clear. However, I still get spurious undesirable scrolling once in a while, not associated with isearch. I don't know what causes that.
