highlight: produce correct markup when there's a blank line just before EOF
Due to how the colorized output from pygments was stripped of <pre> elements,
when there was an empty line at the end of a file, highlight extension produced
an incorrect markup (no closing tags from the fileline/annotateline template).
It wasn't usually noticeable, because browsers were smart enough to see where
the missing tags should've been, but in monoblue style it resulted in the last
line having twice the normal height.
Instead of awkwardly trying to strip outer <pre></pre> tags, let's make the
formatter with nowrap=True, which should do what we need in pygments since at
least 0.5 (2006-10-30).
Example from monoblue style:
Before:
<div class="source">
<div style="font-family:monospace" class="parity0">
<pre><a class="linenr" href="#l1" id="l1"> 1</a> </pre>
</div>
<div style="font-family:monospace" class="parity1">
<pre><a class="linenr" href="#l2" id="l2"> 2</a>
</div>
Now:
<div class="source">
<div style="font-family:monospace" class="parity0">
<pre><a class="linenr" href="#l1" id="l1"> 1</a> </pre>
</div>
<div style="font-family:monospace" class="parity1">
<pre><a class="linenr" href="#l2" id="l2"> 2</a> </pre>
</div>
</div>
(Notice the missing </pre></div> now in place)
