If you follow the POSIX rules for _creating_ tar archives, you cannot
have archivesize % TBLOCK != 0
As we do no longer live in the 1970s, it is obious to test for
impossible things and to warn.....
BSD tar does not work at all when a read size is not a multiple of 512.
Star aborts with an error message is a read(2) returns less than 512 bytes;
this is also true when reading CPIO archives.
