    statements.

commit 08fd3e4ea1565c8674c837cd9e08b1e24f438d33

    Initialize k to get rid of a compiler warning from clang.
    
    The compiler thinks k might not be initialized  because the if on line
    143 might not be true, leaving t uninitialized.  We know that the
    condition is always true because |x| < -2^-28 in the previous line.
