We should probably clear "expect_messages" before creating windows
that use test_proc(), instead of relying on the preceding tests to
clean things up properly. That's not to say we shouldn't clear
"expect_messages" at the "done:" label in test_wndproc() like we do
for "filter_messages" as well though. Also, mode_change_messages[] and
mode_change_messages_hidden[] should be static const. (The reason they
aren't already is probably "windowpos", but there is no particular
reason that couldn't be static as well.)
