bug#64165: ‘minibuffer-message’: naming/documentation bug

[Shynur Xie]

Both the name and docstring of ‘minibuffer-message’ say it uses
minibuffer instead of echo area, but is this really the case?

I enabled ‘global-display-fill-column-indicator-mode’ and want to
disable ‘dispaly-fill-column-indicator-mode’ only in minibuffer, so I
add a function that will turn off that mode to ‘minibuffer-mode-hook’
but it doesn’t work.  I find that if I switch to buffer
“ *Echo Area N*” then disable ‘display-fill-column-indicator-mode’,
the fill column indicator will disappear... So I guess there's a doc
bug.  (<https://emacs.stackexchange.com/questions/77668>)

If I need to guess the issue which confused you, then will it help
saying in the doc string that 'minibuffer-message' works like
'message' when the current buffer is not the minibuffer?

The issue that's bothering me is that both the name and documentation of
‘minibuffer-message’ says that ‘minibuffer-message’ uses minibuffer,
but after adding

    (lambda ()
      (display-fill-column-indicator-mode -1))

to ‘minibuffer-mode-hook’, then executing

    (minibuffer-message "Message Line 1\nMessage Line 2")

I can still see the fill column indicator:

    Message Line 1                  │
    Message Line 2
                                    ^ fill column indicator here

I simply don’t know whether ‘minibuffer-message’ works like ‘message’
when the current buffer is not the minibuffer; I'm not familiar with
how ‘minibuffer’ works.

I think if the documentation directly states: “message is shown in
echo area when the current buffer is not minibuffe” (if indeed this is
the case), it would clarify a lot.

Done on the emacs-29 branch, and closing the bug.

Thanks.
