    podwrapper: simplify external references pointing to self
    
    When convering a POD documentation, possibily combining various
    sub-documents together, simplify the L<> links that explicitly point to
    the very same documentation being generated.
    
    For example, when generating the virt-builder documentation, links like
      L<virt-builder(1)/SECTION>
    will be turned into
      L</SECTION>
    thus not making Pod::Simple parse them as external reference.
    
    While it is a slightly crude hack, it seems there's no easy way to
    process the link parsing with Pod::Simple subclasses.
