Yes, the graphical MINSE renderer currently does grow its grouping
structures. It's the simplest way to facilitate visual matching.

In this case, i think i would prefer if they were. But that's
a matter of taste. This should be configurable by setting style
parameters, something which is easy to do with the extensibility
that MINSE already has. (Download a style file that redefines one
function -- the one for grouping -- and you're done.)

You wouldn't have to worry about this if you treated semi-open
intervals as a compound on their own.
