Knowing the blocking factor used when creating the archive is indeed
essential for successful updating that archive. So, from the point
of view of GNU tar, I wouldn't qualify it as a bug. Nevertheless, GNU tar
could try to guess the blocking factor or, at least to abort without
modifying the archive if its size does not fit the used factor value.
I will try to improve it in this direction.

if they used the same blocking factor.
