You can specify nested subsections. AFAICT, the only option which
currently uses this feature is "g.region -g".

gui.tcl creates a separate frame (within the notebook page) for each
subsection. The end result is that any options within the same
subsection will be grouped.

You can see the effect more clearly if you modify the frame's
properties, e.g.:

--- gui.tcl~	2007-03-23 20:25:13.000000000 +0000
+++ gui.tcl	2007-03-20 17:06:48.000000000 +0000
