Well, it is obviously silly that 

        www.foo.bar.com 
            ***********

would highlight as above.  Or that

        smtp.foo-bar.com

would hit as a web adress. I think a more conservative

        \<www[-a-zA-Z0-9.]*\.[A-Za-z][A-Za-z][A-Za-z]?\>

would hit most of the intuitively obvious http adresses, yet have very
few false hits.  I.e. a word that starts with www and ends with dot
followed by two or three letters.
