Can't crawl a site protected with basic http auth

[changuelsami]

Hi,

My website is protected with a basic http authentification, so when I run this :
./linkcheck https://foo:bar@mysite.tld
I get this error message :
`INTERNAL ERROR: Sorry! Please open https://github.com/filiph/linkcheck/issues/new in your favorite browser and copy paste the following output there:
