1. Let ~/.emacs consist of the following line:
(add-hook 'emacs-lisp-mode-hook 'turn-on-eldoc-mode)
2. Start Emacs with the above init-file.
3. Visit an Emacs lisp file that's long enough to scroll a number of
screens up and down, e.g. lisp/abbrev.el from the Emacs source
directory.
4. Type `M->' (end-of-buffer).
5. Type 'M-v' (scroll-down-command)
=> This puts point at line 902 (at least here, with window-height 33),
which is at the bottom of the window as it should be -- but only for a
fraction of a second, and then point is recentered so that line 902 is
now in the middle of the window.
On subsequent reiterations of M-v this recentering sometimes happens and
sometimes doesn't. I haven't discovered a pattern (nor does it happen
the first time with all files, though it appears to be consistent within
the same file).
This recentering only happens when eldoc-mode is enabled from the mode
hook in the user init file, i.e., starting Emacs with -Q and evalling
the sexp in step 1, then doing steps 2-5, I do not observe the
recentering.
