uri_merge problem with slashdot

["Q. Alex Zhao"]

Hi, I'm using wget-1.7 and found a problem with uri_merge on slashdot
pages.

Basically, slashdot likes to use something like
    <IMG SRC="//images.slashdot.org/topics/topicwine.gif">
Since the referring page is "http://slashdot.org/topics.shtml";,
uri_merge returns
"http://slashdot.org//images.slashdot.org/topics/topicwine.gif";, instead
of the correct "http://images.slashdot.org/topics/topicwine.gif";.

I made some simeple changes to url.c to handle this problem. Thought
you'd like to know.

Cheers.
