[Bug-tar] tar xf and .Z archive

[Karl Berry]

When I run tar tf foo.tar.Z or tar xf on the attached .tar.Z archive
(just an empty file), it says:

tar (child): compress: Cannot exec: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now

But using tar tzf or xzf works.  Maybe that's invoking gzip -d?
In any case, can we make the generic invocation with no z also work in
the same way?

Adobe still uses the old compress program for some current (free)
distributions, and I've had no luck with asking them to use .tar.gz or
.zip.

Thanks,
Karl
