the current lxr seems to have an extra html anchor,
failing HTML 4.01TR validation, because both
Common.pm and html-head.html have that anchor. I'm
using lxr-0.9.2 and according to CVS head, the problem
looks like still exists.
I'm not sure which part of the files is guilty, but I
wanted to let templates to start AND to end an html.
so here is a fix attempt.
