The protection for negligible constraints in the pull calculation used to check for an absolute difference in pre- and post-fit constraint. For most uncertainties this works fine, but if you introduce a param with a value much smaller than 1 the criterion is probably too strict.
This changes the protection to apply if the constraint relative to the input uncertainty is less than sqrt(0.001).
