show unsafe URL

[jidanni@xxxxxxxxxxx]

When we see in gnus
  This link is considered to be unsafe; use the prefix arg to view anyway
we are not shown just where the link will lead to.

E.g., with

      style=3D"FONT-SIZE: 12pt">SIGN THE PETITION&nbsp;<A=20
      =
href=3D"http://www.brusselstribunal.org/Mailing/lt.php?c=3D36&amp;m=3D35&=
amp;nl=3D8&amp;s=3De5bddf7cd3f6106ff54230d3f2cc8f8f&amp;lid=3D151&amp;l=3D=
-http--www.petitiononline.com/GazaSol/petition.html">HERE&nbsp;</A></SPAN=

we are just left staring at the "HERE" while being asked.

(It is bad enough that we are asked twice already.)
