checklink: false positives for broken links

Did linkchecker for http://shadowwalker.info/archives_a.html and it listed
these four supposedly broken links:

Line: 272 http://happyholly.co.uk/FanFiction/2011/10/30/a-matter-of-opinion/
*Status*: 404 Not Found

The link is broken. Double-check that you have not made any typo, or
mistake in copy-pasting. If the link points to a resource that no longer
exists, you may want to remove or fix the link.

exists, you may want to remove or fix the link.
However, only the fourth one is actually broken. Clicking on the links
brings me right to the linked page as it's supposed to.
