hyperbolic: use _coeff_isneg to test sign of leading Number
hyperbolic: use _coeff_isneg to test sign of leading Number

    Although as_coeff_mul removes Rational, it does return -1 off of a
    negative Number (like -4.0 or -oo). This detail no longer becomes
    a concern in reading the code of this file since that is handled
    by the function _coeff_isneg in core.function where a doctest is
    given.
