Bug#443848: XKB grp_led broken in latest packages

[Rich Felker <dalias@aerifal.cx>]

Package: xorg
Version: 1:7.3+2
Severity: normal

Since upgrading to the latest xorg package, the keyboard led
indicators showing the XKB "group toggle" no longer work on my system.
I have grp_led:caps in my configuration but the caps lock light
remains unlit, while the group toggle key itself works.

Simple test to reproduce this:
setxkmap us,el -options grp:caps_toggle,grp_led:caps
Then pressing capslock should switch to Greek keyboard, and the
capslock led should light to indicate Greek layout when it is enabled.

If packagers have trouble reproducing the bug I'll investigate
further.
