Hi...

This patch superseeds my previous patch from here:
http://sourceware.org/ml/insight/2012-q1/msg00031.html

As the old patch is yet not reviewed I reworked it a bit.

The new patch additionally takes also care about the register's window 
changed fields color and it does some minor simplifications.

Changelog:
