Subject: [RFE] (message) should be printing colors
Date: Tue, 25 Feb 2025 21:22:26 +0300

From what I see, both (print) and (message) print colored strings as
non-colored lists in the minibuffer. In batch-mode this information
gets stripped outright. I am not sure what was the reason for the
design decision for batch mode to be different, but since it already
is, let's please make that useful. A code like:

	(message (propertize "This is an error" 'font-lock-face 'error))

…in batch-mode should be colored red.

I am writing some tests, and this is very annoying to search among a
bunch of output the message from the failing test, and printing a
propertized string seems to be the most logical way to make message
colored. But that just doesn't work. Can we please fix that?

AFAIK, we don't support this right now.  Patches welcome.
