* login/logout.c (logout): Do nothing if getutline_r returns ESRCH.

	* login/pututline_r.c (pututline_r): Since we assign RESULT from
	lseek now, check that it's >= 0, not == 0.

Wed Jul  3 13:28:04 1996  Miles Bader  <miles@gnu.ai.mit.edu>

	* login/login.c (login): Make a copy of *UT, fill in various
	fields that we supply (ut_line, ut_type, ut_pid), and use the copy
	in place of UT.

	* login/getutline_r.c (getutline_r): When we return ESRCH, mark
	UTMP_DATA->ubuf invalid (by setting UTMP_DATA->loc_utmp to 0).
