The only other case I could come up with in my regression tests is pretty esoteric:
CREATE COLLATION nulls (locale='C');
ALTER OPERATOR CLASS text_ops USING btree RENAME TO first;
CREATE TABLE nulls_first(t text);
CREATE INDEX nulls_first_i ON nulls_first(t COLLATE nulls first);
I'm not 100% sure there aren't other cases where this can occur though.
Blech. Well, that's why we need to stop hacking the lexer before we shoot a hole through our foot that's too large to ignore. But it's not this patch's job to fix that problem.
