bug#31483: 25.2; handling of links in eww

[Jevon Longdell]

********************************************************
To arrive at this problem I:

1) M-x eww

and gave it the address: ltj.otago.ac.nz

2) Clicked on the link "ELEC441 Course Documents"

It said "Loading http://http:linearsystems/";

Other browsers end up at http://ltj.otago.ac.nz/linearsystems/ which is
where I wanted to go.

I have to admit that I am responsible for this webpage and a bit of an
amateur so it might be my shoddy HTML is at fault. That said all other
browsers I have tried have no problems.

the HTML for the link in that is followed incorrectly is:
<a href="http:linearsystems">ELEC441 Course Documents</a>
