They're not retrieved anywhere.  Support for term_group never fully
materialized.  I think someone is writing a plugin that uses it, but
I'm not sure where that's at or what it's doing.  term_group is just a
simple way of grouping like terms together.  The discussion about
supporting aliasing, term collation, etc. never took off during 2.3
development, so this simple grouping mechanism is what we left it at.
If ya'll have ideas for making this more useful, do tell.
