It turned out that the pixel-based mouse wheel smooth scroll had a
problem: scrolling up the contents of a buffer with a header line is
sometimes jumpy.  Please apply the patch below.  Sorry for the
inconvenience.

(This is due to some incompatibility between Emacs 23 and 24 I
overlooked, so do not apply it to Emacs 23 Mac port 2.1 .)
