Bug#122783: texdoc: use gv if ghostview is not around

[Richard Tibbetts <tibbetts@mit.edu>]

Package: tetex-bin
Version: 1.0.7+20001218-6
Severity: normal

texdoc fails on my machine due to a lack of ghostview, though I have gv.
gv is vastly superior anyways, so it would be cool to use it. And if not
that, then at least depend on ghostview or something.
