?? Sure, that's what psql thinks. But the first case shown above
should also begin a new statement, changing the prompt (it doesn't,
because after stripping the comment there are zero blanks in the
line). I don't think that is the right behavior though.

Things aren't a big problem the way they stand, but istm that a
completely blank line (after stripping single-line comments) may as
well be the same as an empty line,and that psql could figure that out.
