Documentation

The blocksize of tar files written by Emacs, or nil, meaning don't care.

The blocksize of a tar file is not really the size of the blocks; rather, it is the number of blocks written with one system call. When tarring to a tape, this is the size of the *tape* blocks, but when writing to a file, it doesn't matter much. The only noticeable difference is that if a tar file does not have a blocksize of 20, tar will tell you that; all this really controls is how many null padding bytes go on the end of the tar file.
