[PATCH 3/3] add named choice group

From: Roman Zippel
Date: Thu Feb 28 2008 - 23:12:21 EST



As choice dependency are now fully checked, it's quite easy to add support
for named choices. This lifts the restriction that a choice value can only
appear once, although it still has to be within the same group,
but multiple choices can be joined by giving them a name.
While at it I cleaned up a little the choice type logic to simplify it a
bit.
