[xserver-xorg-input-synaptics] Add MatchDevicePath to 50-synaptics.conf

[Sedat Dilek <sedat.dilek@googlemail.com>]

Hi,

while digging trough upstream xf86-input-synaptics I fell over [1]
with a hint to Peters Hutterer's blog-article in [2].

Following the recommendation...

# diff -uprN /usr/share/X11/xorg.conf.d/50-synaptics.conf.dist

Tested with xserver-1.10-rc3, xserver-xorg-input-synaptics
(1.3.99.901-1+exp1) and a linux-next (next-20110311) kernel.

So, it might be good to add MatchDevicePath together with the comments
like in [1] to the Debian package.

P.S.: Attached are my Xorg.logs before and after the change to
50-synaptics.conf file.
