Hmm.  The comment that precedes the disabling of the toggles
in the WriteOut menu says:

    /* If we're using restricted mode, the DOS format, Mac format,
     * append, prepend, and backup toggles are disabled.  The first and
     * second are useless since inserting files is disabled, the third
     * and fourth are disabled because they allow writing to files not
     * specified on the command line, and the fifth is useless since
     * backups are disabled. */

The comment is wrong about the DOS and Mac format toggles: they
have no effect when inserting files, but only when writing out files.

The user can edit the file at will, and save it too, so why not allow
her to change also the format?  She can do it by hand:  M-R  M-R  $
<Enter>  M-V  ^M  <Enter>  A.  Mac format is much more work, but
can also be done.  So why not allow her the convenience of the
toggles?

The comment is also wrong about the append and prepend toggles:
they don't allow writing to other files, they only allow reduplicating
the current file.  This is most likely not what the user wants, so I
think it's good to disable these toggles in restricted mode, but the
comment should be adjusted.
