Subject: [PATCH] A weird hack to work around strange behaviour of xslt on
 empty tags

When you have <xsl:output method="html">, empty tags <foo/> are emitted
as <foo></foo>. These are equivalent as far as XML is concerned, but
browsers expecting HTML will treat this as <foo><foo>.

I considered just having the output method be XML, but this seems to
cause a number of harder-to-address problems on the browser side.
