If there are bugs with handling excluded buffers, I hope we can fix
them, instead of leaving them hidden behind a user option.  People who
will use that option will see those bugs exactly as all of the users
see them today, and they _will_ complain.

OTOH, since no one has yet complained about those bugs, perhaps
leaving this behavior be the default is not such a bad idea?
