Folks,

While testing the upcoming FILTER clause for aggregates, Erik Rijkers
uncovered a long-standing bug in $subject, namely that this case
wasn't handled. Please find attached a patch by Andrew Gierth and
myself which fixes this issue and adds a regression test to ensure it
remains fixed.

Cheers,
David.
