Hard linking messages between maildirs

[Paul Jarc]

I'm a maildir user agent.  I've got a message in a maildir, and my
user wants a copy of it in another maildir as well.  If the maildirs
are on the same filesystem, can I just make a hard link, or do I have
to make a copy?  The maildir specification doesn't explicitly address
this, so a strict reading would say I should make a copy.  If I just
make links, will that break any existing maildir code?
