The bug is specific to successive instances of the exponentiation
operator, a case which requires special treatment to impose the most
common order of evaluation of x^y^z.
I note that this exception of operator precedence is duly mentioned in
the command reference! (Don't just want to speak up whenever something
is missing...)
