    BUG: optimize: fix epsfcn choice in minpack routines

    pv authored
    An additional sqrt() was introduced in 703dc23 --- minpack takes the
    sqrt internally, so it should not be done again.
    The routines can still fail if the problem is badly scaled. The test is
    here changed to be less badly scaled.  The correct choice of epsfcn is
    problem-dependent and in general needs to be left to the user.
    Fixes gh-2639

    Update the parameter documentation in curve_fit

    taldcroft authored
    The documentation describing the `sigma` parameter of the
    `optimize.curve_fit` function was updated to remove the reference
    to representing the standard deviation of the data.  This is 
    misleading because the `sigma` value is used purely as a relative
    weighting factor.
