found in wtmp(5) for the same TTY without in-between "logout"
mark.
This may be demonstrated by executing login(1), logging in and
out, and watching the last(1) output on this TTY:
: # last -tv7 -w
: ru ttyv7 Mon May 28 12:46 - 12:46 (00:00:01)
: ru ttyv7 Mon May 28 12:45 still logged in
The fix merely takes the second "login" mark as the "logout" for
the first "login" mark, if there were no "logout" mark in-between.
This restores the behavior of last.c,v 1.2:
: # last -tv7 -w
: ru ttyv7 Mon May 28 12:46 - 12:46 (00:00:01)
: ru ttyv7 Mon May 28 12:45 - 12:46 (00:00:25)
