Link checking doesn't check the fragment identifier

I opened this against BLC but perhaps it belongs here as it is easier to address for static sites:

Well, the only possibility i see to fix this is to validate the crawled html pages have a corresponding <a> element. HTML parsing and handling is done inside blc, therefore I'd say it should be implemented there. To implement this in the blcl package would duplicate much of the work done inside blc. You may fork it and provide a fix, once it is merged, I'll update the dependency in this package.
