The API defined here (function taking the subject as a string) seems a
bit limited. What if the user wants to use some other message header in
the header-line? Or list tags?

I would complain about missing test, but I think the test machinery
works via buffer-substring-no-properties, which excludes header and mode
lines.

On the other hand, it should be possible to update the manual, at least
with a copy of the docstring.
