Changes in version 0.33:

Long listing format (-vv) has been implemented for '-c, --create' and
'-r, --append'.

'-c, --create' and '-r, --append' now print, with '-v' or '-vv', the member
names as they are archived instead of the names of the files being archived.

The changes above include a refactoring of the code to use the same code to
print the member list when archiving and when decoding the archive.
Therefore '-cvv' should print an identical listing as '-tv'.

'-d, --diff' now compares only the 12 least significant bits of the file
mode stored in the archive. (A tar archive should provide just those 12
bits, but the 'mode' field in the ustar header has room for up to 24 bits).
