Remark: Scaleless zeros need their prescription

Massless one-point and tadpole zeros are retained under the supplied prescription. Scaleless dimensional integrals can vanish by UV/IR cancellation; the integral with integrand $1/(l^2{)}^2$ illustrates the logarithmic issue. No assertion that every scaleless tadpole has no logarithmic UV or IR contribution is used. Insertion problems and infrared rearrangements need their own separation SmirnovChetyrkin.
