There is what may actually be a mistake in our markup. The problem is in a situation like <para> <command>FOO</command> is ... there is strictly speaking a line break before "FOO". In the HTML output, this does not appear to be a problem, but in the man page output, this shows up, so you get double blank lines at odd places. So far, we have attempted to work around this with an XSL hack, but that causes other problems, such as creating run-ins in places like <acronym>SQL</acronym> <command>COPY</command> So fix the problem properly by removing the extra whitespace. I only fixed the problems that affect the man page output, not all the places.
