Bogus argument: if the software is scanning plain text for schemes and
skips over URL:, it also will have skip over lots of places where
sentences end in semicolons:
Like this one.
However it does help point the URL out for human readers, or for making
sure that URLs that are extracted are really intented to be pulled out (so
that we can talk about http://somewhere.com/burp.html in www-talk without
the super new plain text URL extraction software pulling out this duff URL).

I never used to like <URL:....> but since I've started sticking URLs in
bibliographies in printed papers, I've come to appreciate the syntax. The
`<' and `>' server to delimit the (possible multi-line) URL, and the URL:
identifies the string as being a URL which can be passed to a WWW browser
or used with other NIR software. After all there are plenty of people in
Computer Science who still wouldn't recognise a URL as a URL unless it was
pointed out to them. As it doesn't seem to do any real harm by including
it, why not just leave it.
