Spider.HTML.find_links should not collect links to headers

[nappex]

in href we can specify a link to some part of page itself for example headers - You can use href="#top" or href="#" to link to the top of the current page!

But it is not valid link which create valid another page we want to crawl, this kind of page was already crawled.

Shouldn’t it? Although I can’t come up with a real example, there may be a use case. That calls for a switch allowing to enable links without path (and domain, protocol…).
