We are talking about messages in -batch, so stderr.

I don't think we should care.  The primary goal is to have batch-mode
messages to the screen display legibly.  If another program later
examines the results, it's a problem for that other program.  In
particular, if that other program is Emacs, we already have the
solution for displaying these quotes in interactive sessions.
