I see, we need correction: replace the line 'isBinaryInfix op => BREAK()'
in appOrParen by
(op = "-" or op = '"-") and #argl = 1 =>
concat('"(", '"-", appOrParen(first argl), '")")
BREAK was a misguided attempt to catch infinite recursion due to
unhandled cases, and the code did not handle unary minus.
