This should have been done at the time that function was installed. If
you do it now, you may break valid code like
(let (max-chars)
(setq right-fringe-width 0)
(setq max-chars (window-max-chars-per-line))
(set-window-buffer nil (window-buffer))
max-chars)
which currently yields 79 and would yield 80 with your proposal.
