In this case it's more of a termination condition than an error. For
example, the user function may decide that a parameter has gotten out
of bounds unrecoverably. I would like MPFIT to return gracefully
rather than barfing if possible, so the user routine needs a way to
signal MPFIT that something is wrong.
