[NTG-context] Question about \startcombination \stopcombination

Hans,

This is very good point.  Is it an exception for start/start/combination or
a more general difference?  In fact, what are the differences between \X{y}
and \startX y\stopX?  A while back I ran into some weird issues and I
figured that the latter inserts an \endgraf or something like that in the
end.  Is that right?

Thanks,
~MHB
