The problem is that I have to communicate this information in my call to
`format-decode'. Currently we have no way to distinguish cases (2) and
(3) both have `visit-flag' nil. Either we set `visit-flag' to some
constant (say `insert-file-contents-non-visit') for case (2) or provide
an additional argument to `format-decode'.
