You should add

        if (!if_then_else->then_atom)
                die(_("format: %%(if) atom used without a %%(then) atom"));

here ...

Will do.

quoted

+static void then_atom_handler(struct atom_value *atomv, struct ref_formatting_state *state)
+{
+     struct ref_formatting_stack *cur = state->stack;
+     struct if_then_else *if_then_else = NULL;
+
+     if (cur->at_end == if_then_else_handler)
+             if_then_else = (struct if_then_else *)cur->at_end_data;
+     if (!if_then_else)
+             die(_("format: %%(then) atom used without an %%(if) atom"));
+     if (if_then_else->then_atom)
+             die(_("format: %%(then) atom used more than once"));
+     if_then_else->then_atom = 1;

... and

        if (if_then_else->else_atom)
                die(_("format: %%(then) atom used after %%(else)"));

here, just in case (adding the two corresponding test_must_fail wouldn't
harm of course).

Will do, thanks!
