Theorem cdlemefrs32fva 40402

Description: Part of proof of Lemma E in [Crawley] p. 113. Value of 𝐹 at an atom not under 𝑊. TODO: FIX COMMENT. TODO: consolidate uses of lhpmat 40032 here and elsewhere, and presence/absence of 𝑠 ≤ (𝑃 ∨ 𝑄) term. Also, why can proof be shortened with cdleme29cl 40379? What is difference from cdlemefs27cl 40415? (Contributed by NM, 29-Mar-2013.)
