Well indeed it is! However, it states (under 5.005) that the line must
match /^#\s*line\s+(\d+)\s*(?:\s"([^"]*)")?/, when in fact a way too
simple /^#\s*(\d+)\s*(?:"([^"]*)")?/ also works! You forgot to cite the
2nd example from my posting, which showed just that! And this is
definitely hairy and not documented!
