I think that the '-I' should define perfectly the program return values.
So the -I /usr/bin/gzip could be considered like bad usage - and tar
behaves like this now.

Do you want some new "relaxing" option for specifying correct exit values?
Possibly --relax-compressor-exit (or any other idea)?  I'm partly against
this because it complicates tar's api & user is always able to write
very simple wrapper, but I'd be glad to implement it if you don't want to
do it yourself.
