Bug#333960: config script should honour preseeded debconf value for keyboard/options

[Miroslav Kure <kurem@upcase.inf.upol.cz>]

Package: xserver-xorg

Hi,

the config script sets debconf variable
xserver-xorg/config/inputdevice/keyboard/options without actually
checking for existing preseeded value and therefore overwrides it
headlessly.

You can trigger this easily on new installs in Czech where
localization-config sets 
  .../keyboard/layout to us,cz_qwerty
  .../keyboard/options to grp:shift_toggle,grp_led:scroll

but after this config we end up with empty .../keyboard/options, thus
locking users in foreign keyboard layout.


On a similar note, dpkg-reconfigure initializes value of
xserver-xorg/config/inputdevice/keyboard/layout with value based on
installation keyboard and not with current debconf value, which I
consider rather strange.
