GNU Emacs 18.55.121 on NeXT 2

I would like to narrow the writable portion of the buffer without
narrowing the visible portion.  This is useful when you want to edit a
`field': not only does it protect you against stupid errors, it also
means that commands like C-k are useful on the field (which may be
only part of a line).

I'm not sure whether it's better to allow _moving_ outside the
writable part or not.  If you don't allow this, then the package that
does the narrowing has to worry about widening even for read-only, and
you have to re-enter `field edit' mode when you move back into the
field.  If you do allow it, then you have to have some mechanism for
trapping writes outside the protected area and treating them
intelligently (error signalling?).

As far as I can tell, you can't do this in current Emacs.
