bug#61244: 30.0.50; [PATCH] Promote called-interactively-p

FUD surrounding `called-interactively-p` continues to saddle
functions with an incongruous "interactive-p" optional
argument.  `called-interactively-p` is safe enough, and if not,
no one is going to miss whatever trivial behaviors hinge
on its correctness.

 @cindex distinguish interactive calls
 @cindex is this call interactive
 
-  Sometimes a command should display additional visual feedback (such
-as an informative message in the echo area) for interactive calls
-only.  There are three ways to do this.  The recommended way to test
-whether the function was called using @code{call-interactively} is to
-give it an optional argument @code{print-message} and use the
-@code{interactive} spec to make it non-@code{nil} in interactive
-calls.  Here's an example:
-
-@example
-(defun foo (&optional print-message)
-  (interactive "p")
-  (when print-message
-    (message "foo")))
-@end example
-
-@noindent
-We use @code{"p"} because the numeric prefix argument is never
-@code{nil}.  Defined in this way, the function does display the
-message when called from a keyboard macro.
-
-  The above method with the additional argument is usually best,
-because it allows callers to say ``treat this call as interactive''.
-But you can also do the job by testing @code{called-interactively-p}.
-
-@defun called-interactively-p kind
-This function returns @code{t} when the calling function was called
-using @code{call-interactively}.
-
-The argument @var{kind} should be either the symbol @code{interactive}
-or the symbol @code{any}.  If it is @code{interactive}, then
-@code{called-interactively-p} returns @code{t} only if the call was
-made directly by the user---e.g., if the user typed a key sequence
-bound to the calling function, but @emph{not} if the user ran a
-keyboard macro that called the function (@pxref{Keyboard Macros}).  If
-@var{kind} is @code{any}, @code{called-interactively-p} returns
-@code{t} for any kind of interactive call, including keyboard macros.
-
-If in doubt, use @code{any}; the only known proper use of
-@code{interactive} is if you need to decide whether to display a
-helpful message while a function is running.
-
-A function is never considered to be called interactively if it was
-called via Lisp evaluation (or with @code{apply} or @code{funcall}).
-@end defun
-
-@noindent
-Here is an example of using @code{called-interactively-p}:
+  Generally, use @code{called-interactively-p} to determine whether
+the current function's context is interactive.

+  While the call site of @code{called-interactively-p} may lexically
+reside within the body of the subject function, nothing in the Lisp
+runtime links one to the other.  When @code{called-interactively-p} is
+invoked, tracing the stack frame of the subject function is fraught
+given how many intervening function calls could result from arbitrary
+macro expansions, special forms, and advices including those for
+debugging instrumentation.  The heuristics applied cannot guarantee a
+correct result under all conceivable conditions.
+
+  What is guaranteed is a function's lexical environment.  If
+distinguishing interactive is critical, instead add to the subject
+function an optional argument with interactive spec @code{p} (or
+another code that cannot take on a @code{nil} value).  This argument
+is thus assured to be non-@code{nil} when the subject function assigns
