Thanks! That fix took some close reading of the specification, and some
tweaking to some perhaps not-too-obvious code.

Again, I'm following up with a new glcpp test for this, (and a tweak to
a test so that it continues to pass as expected after the change). I'll
try to even get the email threading of my followup correct this time.
