When using protocol-relative links in $wgServer along with DumpHTML extension, the 'Latest revision' tab can end up breaking when viewing the pages on the local filesystem:
<a href="//stormcloud.local/trunk/index.php/Main_Page">Latest revision</a>
ends up resolving the URL in the browser to something like:
which doesn't work too well.
Should probably use $title->getCanonicalURL here.
