[Message part 4 (text/plain, inline)]

Recipe from "emacs -Q":

1. Eval: (setq scroll-conservatively 101)
2. Eval: (setq scroll-margin 1)
3. Eval: (custom-set-faces '(mode-line ((t (:box (:line-width 1))))))
4. Visit the attached file (c-mode should be activated automatically).
5. Type: `C-s p'

The point jumps to line "/*p1*/" but an instant later the buffer is
scrolled vertically by 1 line.  This last scrolling should be avoided,
i.e., the buffer should be displayed in the right position without
having to correct its location afterwards.
