Hi,

I found this while playing with LaTeX:

Version 6.1 of TeX/LaTeX and release 1.8 of Psfig/TeX (psfig.tex) together
allow the ability to include compressed ps files.  When TeX realizes that it
has a compressed file, it prints out a series of special commands to handle
uncompressing the file.  In particular, "ps: plotfile "`zcat filename"".

The problem occurs when xdvi (version 1.5 and version 1.7)) trys to parse
this special command.  There currently does not exist any special
consideration for this case.  What happens is that when parsing the special
command, it thinks that the filename is "`zcat" and trys to open that file,
and of course can't find it.  If you look at dvips (version 5.526a) in the
file dospecial.c in function dospecial, you will see that this case is
handled.  It flags the "`zcat filename" as a special case and uses a call
to popen (in function copyfile in output.c).  This allows the "zcat filename"
command to be executed and then dvips just reads the uncompressed input
from the pipe.

Would it be possible to have xdvi handle this case also?

Thanks,
