svn commit: r299713 - head/usr.sbin/timed/timed

[Pedro F. Giffuni]

New Revision: 299713
URL: https://svnweb.freebsd.org/changeset/base/299713

Log:
  Undo the bogus gethostname() change from r299709.
  
  The "- 1" is there specifically to enable checking for NUL termination.
  
  I should also admit the rest change was mostly cosmetic and the
  overruns can't occur in practice: still I leave them to pacify
  static analyzers.
