[PATCH 3/3] write_in_full: size_t is unsigned.

It received the return value from xwrite() in a size_t variable
'written' and expected comparison with 0 would catch an error
from xwrite().

Signed-off-by: Junio C Hamano <redacted>

 * and this is the third bug t7207-co.sh caught.  I haven't
   bothered to look at the assembly, but I suspect the error
   return path could have been totally optimized out X-<.
