Subject: bug#79469: 31.0.50; Ungrammatical sentence from describe-function
Date: Thu, 18 Sep 2025 18:41:16 +0200

[Message part 1 (text/plain, inline)]

Calling `describe-function' on a noninteractive non-byte-compiled
function produces an ungrammatical sentence in the *Help* buffer:

0. emacs -Q
1. Load a non-byte-compiled file that contains a noninteractive function
   definition, e.g. edt-user.el from the Emacs "etc" directory.
2. Call `describe-function' on a noninteractive function from that file,
   e.g. `C-h f edt-setup-user-bindings RET'.
==> The *Help* buffer now begins with this sentence:

edt-setup-user-bindings is a interpreted-function in
‘~/src/emacs/emacs-master/etc/edt-user.el’.

It should say "...is an interpreted-function...".

Here are three possible fixes:

[Message part 2 (text/x-patch, attachment)]

[Message part 3 (text/x-patch, attachment)]

[Message part 4 (text/x-patch, attachment)]

[Message part 5 (text/plain, inline)]

Of these three I prefer the first, since it directly generates the
correct string, while the other two change an incorrect string to the
correct one.

While all three are ad hoc fixes, I think the undoubted complexity of a
more general fix is unjustified here, because (unless I've overlooked
something) `interpreted-function' is the only function type symbol
returned by `cl-type-of' in `help-fns-function-description-header' that
results in the problem (since it begins with a vowel).
