Subject: 30.0.50; fido-mode errors when case-fold-search is nil
Date: Mon, 18 Dec 2023 21:10:24 +0100

Hi,

If global case-fold-search is nil, fido-mode throws errors when typing 
upper case letters or on candidates with upper case letters.

Reproduce with: emacs -Q, then:

(fido-mode 1)
(toggle-case-fold-search)

;; then execute:
;; M-x <T or t or another pattern>

Which produces messages like:
> Error in post-command-hook (icomplete-post-command-hook): (error 
"Internal error: \\`\\(.*?\\)T does not match cpp-parse-edit")
> Error in post-command-hook (icomplete-post-command-hook): (error 
"Internal error: \\`\\(.*?\\)t does not match LaTeX-mode")

Many thanks!

Thanks.  Reproduced.  I think the error specifically was due to
recent changes in Emacs master.  In Emacs 29, fido-mode doesn't
error, but doesn't respect case-fold-search either.

I fixed the recently introduced error in Emacs master (c0c79b0b4).

I may have mislead you to think there was also a problem in Emacs 29,
but there isn't.  Completion styles obey completion-ignore-case,
not case-fold-search directly.

Furthermore, while the flex completion style does obey it, fido-mode
(which is a "Fake Ido" extension) always sets completion-ignore-case
to t by default.  There are ways to get around it, admittedly
not very practical, but not terrible either.

  (defun joaot/minibuffer-setup-hook ()
    (setq-local completion-ignore-case nil))
  (add-hook 'minibuffer-setup-hook #'joaot/minibuffer-setup-hook t)

Nice. Anyway, for me ignore case in minibuffer is the most suitable 
method, and maybe for most people too.
