Hrm. So you dislike my patch about clearing buffers so much that you ignore
its existence ? You could have suggested to add a new full_clear function in
Hrm. So you dislike my patch about clearing buffers so much that you
ignore it ?

People could have suggested to add a new full_clear function in addition
to the CAP I proposed, rather than the CAP modifying the behaviour of
the existing clear function (which was, admittedly, probably a bad idea).
