Well, of course, not _strictly_ the same -- there is some danger that
when one wants to prevent modification of an invisible part of an
editable buffer, using only Stefan's definition will cause odd
side-effects because some low-level functions will stumble into the
invisible part, even though the user can't do so (because with Stefan's
code, point adjustment is part of the command loop).

Whether this will be a problem in practice, I don't know.

Occam's razor split hairs so well, I bought the whole argument!
