Very strange.  On my system, with acceleration turned on, one click
scrolls about 2 to 7 lines in several applications I tried.  Emacs
scrolls 5, and so does Firefox.

Not here.

I'm not sure what to make of this issue.  It seems the results of
scrolling by the wheel differ widely across systems, so customizations
are necessary in any case, and altering the defaults will not change
that.
