You are right :)

Ok, I've done the patch, works good for me, see
http://bugs.freedesktop.org/show_bug.cgi?id=865#c45. It would be nice if
someone review it.

One issue with the patch: "switch on release" behaviour is hard coded
(but can be easily turned off by xkbSwitchGroupOnRelease() function!).
How to do it? The very simple and dirty way is to turn on/off via ...
XkbSetDebuggingFlags() function only but it is not good.
Standard XKB configuration is not good for it too.
