Then why do all the other Message mode faces
work as expected, but this doesn't?

And why does it work to change the face when
`mail-header-separator' is at its original
"--text follows this line--", but not when
changed to "---" or any other value for
that matter?

If it isn't a bug, perhaps we should have a new
list/newsgroup called
gmane.emacs.wierd-behavior where we can report
this kind of things in good order?
