Subject: 29.0.91; icomplete-mode ignores minibuffer-completion-confirm
Date: Mon, 05 Jun 2023 15:39:42 +0200

The problem is that setting the variable `minibuffer-completion-confirm` to
'confirm is not respected by icomplete-mode.

Steps to reproduce:

1. Evaluate following lines:

(setq minibuffer-completion-confirm 'confirm)
(icomplete-mode)

2. C-x C-f /tmp/non-existent-file

The documentation string of `minibuffer-completion-confirm` states:

  If the value is 'confirm', the user may exit with an input that is not a valid
  completion alternative, but Emacs asks for confirmation.

Since a file is opened which does not exist, I would expect that after pressing
RET the first time, Emacs still stays in the minibuffer and appends [Confirm] at
the end of the line. Only when pressing RET a second time Emacs switches to the
new buffer.

The actual behavior is that Emacs directly switches to the new buffer without
confirmation after pressing RET for the first time.
