Log Message:

Redesigning color support in troff.  Colors are no longer
represented as separate nodes but are now part of glyph nodes and
friends.  This fixes the current formatting misbehaviour due to the
changes introduced on 2002-09-20.  Some extra code is necessary for
proper grotty support: Without adding color variables to
space-related nodes, the background color would be changed too late.
