[PATCH 3/5] status: refactor null_termination option

From
Jeff King <peff@peff.net>
Date
May 7, 2012, 21:24 UTC
Message-ID
<20120507212423.GC19567@sigill.intra.peff.net>
In-Reply-To
<20120507212125.GA19532@sigill.intra.peff.net>

This option is passed separately to the wt_status printing functions, whereas every other formatting option is contained in the wt_status struct itself. Let's do the same here, so we can avoid passing it around through the call stack.
