Subject: [PATCH] BLFS tools: don't generate duplicate download code

For additional downloads, the normal book layout is a <bridgehead>
containing "Additional Downloads" followed by one or more
<itemizedlist>, one for each file to download. But on some pages,
there are several <bridgehead>, each followed by one or more
<itemizedlist>. So we have to check that only the <itemizedlist>
correponding to the current <bridgehead> are treated. Otherwise,
the download code may be generated more than once. This imposes
that no other bridgehead is inserted between the one containing
"Additional" (or in some case "Recommended/Optional Download") and
the <itemizedlist>.
