commit c649f7f5c4f5b74d48efa3453c38c1458e7ae9a9

    T-TEST: Avoid NaN in paired-sample correlation significance calcuation.
    Sometimes the correlation comes out just above 1.0 due to inaccuracy of
    machine calculation, which causes sqrt(1-corr**2) to yield NaN.  This
    commit forces the correlation into the valid range, fixing the problem.
    Thanks to Matej Cepl <address@hidden> for reporting the problem.
    Thanks to John Darrington for suggesting the fix.
