This change added an extra blank line to the output of a zero-row result.
Compare:
[9.4]
$ psql -X -d postgres -c 'select * from pg_class where false' -x
(No rows)
$
[9.5]
$ psql -X -d postgres -c 'select * from pg_class where false' -x
(0 rows)
$
Was that intentional?
That's consistent with what > 0 rows does, so it seems the correct thing
to do. Going from "(No rows)" to "(0 rows)" is going to break things
anyway, so I don't see a backwards compatibility issue here.
