Poking into this revealed what seems to be a long-standing bug: a view
that uses BETWEEN gets confused about any variables appearing in the
first argument of the BETWEEN.  I've fixed this in current sources,
but for 7.0.* you'd be best advised to write out BETWEEN explicitly
as "a >= b AND a <= c".

A separate issue is that grouped views don't work very well in 7.0.*.
This is also fixed for 7.1, but in the meantime don't expect to be able
to apply aggregates or grouping to the output of a grouped view.
