Yep, strncpy may not NUL terminate,
so using it is awkward as detailed here:
http://www.pixelbeat.org/programming/gcc/string_buffers.html

stpcpy/stpncpy are appropriate here as the buffer is just
the right size, so you don't waste cycles filling with NULs etc.

Often it's simpler/faster to fall back to memcpy for C string buffers
as I did in buffer_or_output() here:
http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commitdiff;h=b1428e31

patch looks good.

cheers,
