Tracey:

Note that this won't cope with some of the more pathological URLs (such as
those with CGI arguments [http://system/cgi?arg1=val1] or those which link
to a named anchor in the target page [http://system/pageref#target-name]).

Since it's about six times better that anything I could do, however, let
this act as a caution rather than a correction.
