[Message part 1 (text/plain, inline)]

Recipe from "emacs -nw -Q" (the "-nw" part is not strictly needed, but
it is cleaner for showing the problem):

1. Visit the attached file.
2. Adjust the vertical space (empty lines) between "first line" and
"last visible line" until the latter becomes indeed the last visible
line in the window.
3. Go to the start of the buffer: M-<
4. Advance one line: C-n
5. C-s 1
6. C-g

I observe that after step #5 the window is scrolled (OK), and that
scrolling is cancelled after step #6 (OK - like it should be).

But if I set `scroll-conservatively' to 1 and repeat the experiment
(from step #3), I observe that the vertical scrolling made in step #5
is not cancelled in step #6.  IMO it should be cancelled, because
"C-g" should leave the view (not just the point) where it was before
the Isearch.
