I am creating a set of manpages to document D-Bus interfaces. To do this I am using DocBook refentry containing lots of methodsynopsis elements. I ran into two issues with the manpage output of methodsynopsis not present in the (X)HTML output (the only other one I tried). Both are to do with missing line-breaks when viewed with the "man" program.
I have attached my local patch to take care of this, although the first delta is a bit hacked due to the situations when I need the line breaks. There may be just a general need for a line break after every methodsynopsis usage.
