@alexanderlukanin13 , I've been looking at the recent Travis build failures
(working on these changes: https://github.com/scrapy/scrapy/pull/570)

The last one that's bugging me is this repetition link from `sgml_linkextractor.html`

According to https://github.com/scrapy/scrapy/blob/master/scrapy/contrib/linkextractors/sgml.py#L50
```
links = unique_list(links, key=lambda link: link.url) if self.unique else links
```
shouldn't the extractor pick up the non-"repetition" link?
