Hi,

I've been working on an implementation of MINUS recently, and found
the existing SPARQL tests did not cover a number of cases. I'd like to
suggest the following tests: full-minuend, part-minuend. (files
included below)

These two queries cover a number of conditions each. Alternatively,
each case tested in these queries could be pulled out individually.

Regards,
Paul Gearon
