Need of a "nil" body to close a tag

[vindarel]

Hi,

edit: I was traped by something not identified in this message.

it wasn't obvious to me that tags are not closed if they have no body:

(markup (:br))
;=> "<br />"

whereas

(markup (:br nil))
;=> "<br></br>"

This can be an issue for html generation and is surely a trap easy to fall into.

It doesn't help to set the style:

(eval-when (:compile-toplevel :load-toplevel :execute)
  (setf *markup-language* :html))
(markup (:p))
;; => "<p>" (and nothing closing)

So am I doing sthg wrong and is it possible to have auto-closing tags with no body ?

It would be helpful if this was included as part of the README. Some html tags e.g. textarea, seem to require explict closing tags.
