Subject: 29.0.60; Problems navigating completions from minibuffer with flex
 completion style
Date: Sun, 25 Dec 2022 16:48:31 +0100

Selecting completions from the minibuffer with M-<up>/<down> and M-RET
doesn't always work quite the way I expect when the flex completion
style is used. For example:

1. Evaluate: (push 'flex completion-styles)

2. Type: M-x c++-mode TAB TAB
   (The *Completions* buffer now shows three alternatives: c++-mode,
   c++-ts-mode, c-or-c++-mode.)

3. Type M-<down> to select c++-mode, and then M-RET.

Expected result: c++-mode is enabled in the buffer.

Actual result: An error with the following message is raised:
‘c++-modemode’ is not a valid command name

To be able to fix this, we need to install
at least some parts of the patch proposed in
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=48356#40
Probably too late for Emacs 29.

Looks like this is fixed now, probably in bug#62700.
At least, I can't reproduce the problem.
Please reopen if you still see it.
