* doc/coreutils.texi (stat invocation): Add sentence-ending period.
* NEWS: Correct stat change description: s/floating point //.
* cfg.mk (old_NEWS_hash): Update, to match this NEWS change.

   stat's %X, %Y, and %Z directives once again print only the integer
   part of seconds since the epoch.  This reverts a change from
-  coreutils-8.6, that was deemed unnecessarily disruptive.  To obtain
-  a nanosecond-precision floating point time stamp for %X use %.X;
-  if you want (say) just 3 fractional digits, use %.3X.  Likewise
-  for %Y and %Z.

   stat's new %W format directive would print floating point seconds.
   However, with the above change to %X, %Y and %Z, we've made %W work
