Thanks for the confirmation, at least.

Too bad about the buggy behavior and the doc mismatch. Apparently this has been
a problem since the introduction of the feature (`scroll-margin' etc.) in Emacs
22. If no one has the time to understand it and fix it, perhaps this code should
be reverted to pre-Emacs 22?
