I don't like this output. If there are a lot of sort keys, it gets
difficult to match the right ASC/DESC element to the sort key it applies
to. (Also, there seems to be double-spaces in the list)
I would suggest just adding the information to the Sort Key line. As
long as you don't print the modifiers when they are defaults (ASC and
NULLS LAST), we could print the information even in non-VERBOSE mode. So
it would look something like:
Sort Key: sortordertest.n1 NULLS FIRST, sortordertest.n2 DESC
