Ack, you're right! I saw the test_window_style() but second-guessed 
myself and put it into test_reset() instead... That was foolish of me. 
Thanks.

I'm a bit confused, then: Without this change, the exstyle test breaks, 
and the guidelines request that every patch be atomic. They also request 
that all tests be included in the same patch.What is the proper 
procedure for this when it comes to multipatch patchsets?
Off the top of my head, I would guess it's one of these:
1. The "all tests in the same patch" rule is only appropriate for 
single-patch submissions, so in multipatch patchsets, it's acceptable to 
include a final patch with nothing but tests.
2. Only introduce the tests in the last patch of the patchset. (That is, 
add them all at once, but only when all of the necessary changes have 
been made to allow the tests to work first.)
3. Include each test in the first patch that will allow the test to 
pass. (That is, add them incrementally.)
4. Add the tests as todo_wine in the first patch, then remove the 
todo_wine in later patches as each test becomes functional. (That is, 
add them all at once as todo_wine, and mark them as non-todo incrementally.)

Done. :)

Thank you,
