Well given that this is derived from blueprint css I take it that it
was used ideas from an A List Apart article on print css styles. In
it, they talked about how hyperlinks is tricky because how would you
show what it leads to if you it's printed out? You could just take out
the style and pretend it's regular text, or you can do what that line
did: print out the href of the link so at least you know where the
link leads to.
