It does not seem to be a bug. As mentioned in a previous message
<https://lists.debian.org/debian-user/2017/08/msg00404.html> what
happens is that in Debian 9, mouse acceleration parameters are handled
by libinput by default (I think that one can disable libinput by
replacing the package “xserver-xorg-input-libinput” with
“xserver-xorg-input-evdev”, but I beware that I have *NOT* tried it)

Apparently, libinput uses its own parameters and ignores the parameters
that “xset” alters.
