Comment 12 for bug 85650

I'd like to add that a URL that begins with "//" can be well-formed. For example,

//example.com/somepage.html

is a link to /somepage.html on the host example.com *in the same protocol*. That is, on

https://example.org/index.html

the link would go to

https://example.com/somepage.html

instead of the http:// variant.
