[Bug-cpio] wanted overflow in code produce gcc warning

[Ladislav Michnovič]

Hello.

As it is written in src/tar.h where is explained the header structure
in the commented text
then the file src/tar.c line 220:
      strncpy (tar_hdr->magic + TMAGLEN, TVERSION, TVERSLEN);
can be written this way:
      strncpy (tar_hdr->version, TVERSION, TVERSLEN);

I assume the author intended to copy the TVERSION to tar_hdr->version.
Gcc 4.3 produces  a warning about overflowing which is correct but the
overflow is  wanted.
I would preffer to rewrite it to silent gcc compiler  warnings and it
would be IMHO clearly readable for others. Thank you.

Regards Ladislav.
