The purpose of the end-of-tape script is to inform the operator about
the fact that the tape has finished and make sure the fresh one is
provided. The only thing that matters for tar is the script exit value:
if it exits with 0, tar continues the operation, otherwise the operation
is aborted. The script runs with stdout and stderr connected to the
terminal, so whatever it prints is meant to draw attention of someone
who's in charge of the backup.
