When solving ?id{args} = ?id'{args'}, give preference to ?id:=?id' if
possible, which is the "natural" way to orient an equation. At least
it matters for matching subterms against patterns, so that it is the
pattern variables which are substituted if ever the subterm has itself
existential variables, as in:
Goal exists x, S x = x.
eexists.
destruct (S _).
