Interesting idea, I hadn't thought of that.

I currently don't do anything with the results of the ADQL parsing
except for hightlighting syntax, but I don't see any reason that
I shouldn't.  From a quick look at the parser API, it looks like it's
as simple as using the hasLimit/getLimit methods on the result
of ADQLQuery.getSelect() - is that right?

(incidentally - I see that getLimit returns int, maybe one day
someone will wish that was a long?)
