Subject: [PATCH] who: fix only-theoretical overflow
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Change stzncpy’s implementation to match its comment, in the case
where SRC + LEN would overflow.  This case never happens in coreutils.
* src/system.h (stzncpy): Work even if SRC + LEN would overflow.
