That's why I wanted to say _extra_ empty tags.

Well, I still think that your idea of "unclosed tags" is just like
my idea of "empty tags".

I wanted to name it `sgml-extra-empty-tags' because from
sgml-close-tag's point of view (and sgml-tag's point of view, as far
as I can tell), it has the same purpose as `sgml-empty-tags'.

That (sgml-indentation) would be difficult: either we add a function
which parses a dtd (but IMHO that is PSGML's purpose) or the user
will have to specify everything. I guess you know that ;-)

That was not my point. I was just saying that it is less disturbing
if it is called sgml-close-tag-* because users will know that it is
only relevant in `sgml-close-tag'.
