[Bug-tar] no error message when running out of space if -z is used

[Noah Romer]

Ok, I came across this issue today:

If I tell tar to create a compressed archive (tar -czvf) on an nfs mounted 
partition that lacks sufficient space for the tar file, it processes all 
listed files (even long after it ran out of space), returns zero and does not 
print out an error message. It still returns zero if I don't tell it to 
compress the archive (tar -cvf), but it does, at least, print an error 
message, "Warning: Cannot close: No space left on device" . However, if this 
occurrs on a directly connected partition, the expected error messages are 
seen.

If I run stand alone gzip on a file in the above situation, it does detect 
that it's run out of space.
