Re: Possible bug

    < The variable compilation-scroll-output controls whether Emacs tracks
    < the tail of the messages or not.

    $ emacs -Q #using snapshot of late Sep 2006, sorry
    (set-variable (quote compilation-window-height) 111 nil)
    (compile "seq 222" nil)
    And it still tracks the bottom, even though
    compilation-scroll-output is nil, as default.

Using
Today's GNU Emacs CVS snapshot, Thu, 2007 Jan  4  11:19 UTC
GNU Emacs 22.0.92.14 (i686-pc-linux-gnu, GTK+ Version 2.8.20)
started with

    /usr/local/src/emacs/src/emacs -Q -D \
    --eval '(setq-default mode-line-buffer-identification
            (quote (#("%14b" 0 4 (face (:weight normal))))))' \
    -fn "-Misc-Fixed-Medium-R-Normal--20-200-75-75-C-100-ISO8859-1"

in a compile with 

    (setq compilation-scroll-output nil)

point stays at the top of the *compilation* buffer window;
and in a compile with

    (setq compilation-scroll-output t)

point tracks the bottom.

This is what is supposed to happen and no change is needed for the
current CVS Emacs.

    (set-variable 'compilation-window-height 111 nil)

sets compilation-scroll-output to a non-nil value, so we should expect
point to track the bottom.  As describe-function says

    (set-variable VARIABLE VALUE &optional MAKE-LOCAL)

    Set VARIABLE to VALUE.  VALUE is a Lisp object.
