From 52a5d1f981236517b295badcb96bbbd5734b2fd0 Mon Sep 17 00:00:00 2001

Subject: [PATCH] sequence_of_no_tagvars declared variables used only in
 end_sequence_of_no_tagvars and only as unnecessary temporaries, so get rid of
 them; also, push most of the work of the latter macro into a helper function.
