Bug#363248: dexconf ignores mouse settings from debconf

[EspeonEefi <espeoneefi@eep.dnsalias.org>]

Package: xserver-xorg
Version: 1:7.0.18
Followup-For: Bug #363248

I was encountering this same problem, so I dug into /usr/bin/dexconf a 
bit. I found this really strange section (starting from line 271):

### MOUSE / INPUTDEVICE

DO_EMULATE3BUTTONS=

fetch xserver-$SERVER/config/inputdevice/mouse/port
MOUSE_PORT="$RET"
fetch xserver-$SERVER/config/inputdevice/mouse/protocol
MOUSE_PROTOCOL="$RET"
fetch xserver-$SERVER/config/inputdevice/mouse/emulate3buttons
if [ "$RET" = "true" ]; then
  DO_EMULATE3BUTTONS=true
fi

exec 4>"$DEXCONFTMPDIR/InputDeviceMouse"
cat >&4 <<SECTION
Section "InputDevice"
	Identifier	"Configured Mouse"
        Driver		"mouse"
        Option		"CorePointer"
        Option		"Device"		"/dev/input/mice"
        Option		"Protocol"		"ExplorerPS/2"
SECTION
if [ -n "$DO_EMULATE3BUTTONS" ]; then
  printf "\tOption\t\t\"Emulate3Buttons\"\t\"true\"\n" >&4
fi
printf "EndSection\n" >&4

It seems as if dexconf is simply ignoring the values for Option "Device" 
and Option "Protocol" that it's pulling from debconf. Is this actually 
an intentional behavior?
