Bug#2122: xdvik doesn't handle the `zcat convention

[fonseca@acse.shef.ac.uk (carlos fonseca)]

Package: xdvik
Version: 18f-4

xdvik does not handle the `zcat convention (used in postscript specials
for including compressed .eps figures) correctly. As a result,
compressed figures included in my older dvi files (produced with
latex209)  are not found, although they are there, and an older xdvik
does display them.

This is a bug in xdvik-18f itself (the docs say it should work). The
attached patch corrects the problem.  As I have not notified the
original author of the package, I wonder whether this report will be
propagated to him for inclusion in a future release.
