	Fuse edges (in a wire) of a shape where we have useless vertex. In case face <FF> is built on UV-non-connexed wires (with the two closing edges FORWARD and REVERSED, in spite of one only), we find out the faulty edge, add the faulty shapes (edge,wire,face) to <MshNOK>. <FF> is a face descendant of <F>. <MWisOld>(wire) = 1 if wire is wire of <F> 0 wire results from <F>'s wire split. returns false if purge fails.
