* --test-label behavior
In case of a mismatch, `tar --test-label LABEL' exits with code 1,
not 2 as it did in previous versions.
The `--verbose' option used with `--test-label' provides additional
diagnostics.
Several volume labels may be specified in a command line, e.g.:
tar --test-label -f archive 'My volume' 'New volume' 'Test volume'
In this case, tar exits with code 0 if any one of the arguments
matches the actual volume label.
* --label used with --update
The `--label' option can be used with `--update' to prevent accidental
update of an archive:
tar -rf archive --label 'My volume' .
This did not work in previous versions, in spite of what the docs said.
