Inverted mouse wheel since refurbishment of moused?

A while ago /usr/sbin/moused has seen some refurbishment. Since then in X11 the mousewheel is
inverted. I'm on CURRENT and 15-STABLE. Mouse is right hand. Moving the wheel "away" was
supposed to scroll DOWN towards the last entry (i.e. within an xterm), moving (or rotating, if
you like) the wheel towards me was supposed to scroll UPWARD towards historical entries. Up to
the time of this inversion there was no difference between Microsofts handling of the
mousewheel. Now, switching between M$ Windows and my lab's FBSD installation is a pain, my
limited brains capacity doens't compute the inversion of the axis very fast. Since I do not
use fancy things on how to configure the mouse in Windows I suppose its the standard how I
use the mouse (I use Windows for department's Email, just that), in FreeBSD's X11 I used for
years now either no extra config or  

Option "ZAxisMapping" "4 5 6 7".

First guess was to shuffle "4 5 6 7", but whatever the order of the numbers is, it has no
effect.

What triggers this inversion  and how to restore the "legacy" or, more suitable, the
traditional way?

Thanks in advance,
Oliver
