I like the Message-Id tag.  It means you can `b4 mbox <mesg-id>` and get
the thread.

Linus has complained (rough remembering) that everyone is using the
Link: tag for links to the patch itself.  It's supposed to be for Links
to bugzilla or to the spec or whatever.  Extra information, too much to
put in the commit message.  Now the Link tag is useless because it either
points to the patch or to a bugzilla.  Depend on what you want it to do,
it *always* points to the opposite thing.

But I can't remember what people settled on as the alternative to use
to link to lore...

In theory, we should be able to figure out the link to lore automatically
and there have been a couple projects which tried to do this but they
can't make it work 100%.  Maintainers massage and reformat the patches
too much before applying them.
