description:
Pull up following revision(s) (requested by chs in ticket #1137):
        usr.bin/finger/util.c: revision 1.29
in find_idle_and_ttywrite(), initialize idletime and writable to 0
when stat() fails.  this prevents a coredump later in stimeprint()
due to gmtime() returning NULL for an uninitialized idletime.
