Version: 29.0.50
Severity: wishlist
Tags: patch

To address several requests, there is a patch for Emacs 29 that supports:

1. inhibiting messages selectively like discussed in bug#42865, bug#44629;

2. multi-line accumulated messages like discussed on emacs-devel
   under subject "Intelligent stacking of messages in the echo area";

3. combining all them plus minibuffer messages into a pipeline:
   first inhibit-message can filter out some messages, then the second
   function can accumulate 10 old messages into a multi-line message,
   then the third function will display them in the active minibuffer.

By default, 'set-message-functions' will be '(set-minibuffer-message)'
with the current behavior, but can be customized to
'(inhibit-message set-multi-message set-minibuffer-message)'
to implement the hook-like list of functions described above:
