These changes allow for sshrc to work with SunOS 5.10 as that version does not have all the current day flags that tar has. This will give greater compatability and may improve other compatability. This converts from:
tar cfz - -h -C $SSHHOME $files
to
{ cd $SSHHOME; tar cf - -h $files; } | gzip
and reverses the order (gunzip followed by untar) for the final unpack.
