tweaks: avoid a warning on newer compilers, by writing an extra byte

Browse Source 
When the version number is a trio, the version string will occupy
ten bytes and the terminating NUL byte would not be written (which
was not a problem as byte 12 of the lock data is zero anyway).
But it's better to not have the compiler complain, so allow writing
the terminating NUL byte outside of the ten bytes reserved for the
version string.
