Theorem cdlemefs32fvaN 35710

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 35316 here and elsewhere, and presence/absence of s .<_ ( P .\/ Q ) term. Also, why can proof be shortened with cdleme27cl 35654? What is difference from cdlemefs27cl 35701? (Contributed by NM, 29-Mar-2013.) (New usage is discouraged.)
