It's a trigger for scripting which was not properly designed to have a 
fall back.

They are often used to do things like popups.  Some text mode browsers 
recognize the pattern of the scripting code that is often used in these 
cases, and because there was no fundamental need for scripting are able 
to pull out the link that they are really implementing.  They basically 
have very shallow "Javascript" processing that doesn't understand the 
language but can recognize some common patterns.

RFC1855 says there should be an address here, but, in a world of spam,
that is no longer good advice, as archive address hiding may not work.
