bug#73470: Rmail is not working with maildirs

[Marc Coquand <marc@mccd.space>]

Version is GNU Emacs 29.4 (build 2, x86_64-unknown-linux-gnu, X toolkit,
cairo version 1.18.0) of 2024-06-25.

I was able to change so I can read the inbox, I can read inbox files by
changing the command to

(setq rmail-primary-inbox-list
'("maildir:///home/mccd/mail/home/INBOX"))

Ideally though it'd be nice to have all email available from the
subdirectories as well. Perhaps this is not supported by Rmail.

This is the messages output:
Wrote /home/mccd/RMAIL
Computing summary lines...done
X new messages read
Making completion list...
