`shr-next-link' and `shr-previous-link' currently skip over links that
are contiguous with the current link.  The attached patch addressed this
problem.

When I say "contiguous", I'm talking in terms of Emacs "positions"--not
in terms of HTML.

P.S. I'm still waiting for my boss to return the copyright disclaimer
form to me.  Hopefully this change is minor enough...
