24.3.50; About an example in "(elisp) Writing Emacs Primitives" |

In (info "(elisp) Writing Emacs Primitives"):
INTERACTIVE
This is an interactive specification, a string such as might be
used as the argument of `interactive' in a Lisp function. In the
case of `or', it is 0 (a null pointer), indicating that `or'
cannot be called interactively. A value of `""' indicates a
function that should receive no arguments when called
interactively. If the value begins with a `(', the string is
evaluated as a Lisp form. For examples of the last two forms, see
`widen' and `narrow-to-region' in `editfns.c'.
In the last sentence, neither the INTERACTIVE of the example primitive
`widen' nor `narrow-to-region' begins with a `('. I think
`narrow-to-region' should be replaced by primitives like `insert-char'
instead.
