Well, somebody thought it would be a good idea to place a field property
on "-- " and I guess there were reasons. Maybe one effect is that it
supresses whitespace cleanup (the trailing space is significant), and
paragraph filling.

Yes, that's controlled by `message-beginning-of-line'.

Maybe. Or an nonintended side-effect. If it bothers you, file a bug
report.
