kick hotkeys on release, not press bug

[yan]

Dear X.org developers!

I'm regular Linux user from Russia. Since I'm Russian I use two keyboard
layouts (Russian Cyrillic and ANSI US). As an ex-windows user I'm used
to switch them with Ctrl+shift kb combination (alt+shift is popular as
well). This shortcut is popular among users, but there is a problem with
X.org with it. If you use this shortcut as a layout switcher other
shortcuts with ctrl and shift won't work.

There is a bug (https://bugs.freedesktop.org/show_bug.cgi?id=865) that
exists for 14 years! And the patch exists for about 10 years. This patch
is applied to Ubuntu distro since 2010. But unfortunately no one willing
to merge it. One of the arguments for rejecting this changes is standard
breakage.

I would like to see it merged and as a compromise I suggest an option in
xorg.conf or ifdef. Can anyone help to get it merged and close this
issue. I will be glad to provide all necessary code changes since I'm
C++ programmer.

Regards,
Yan
