TEST: finger-0.17-24

[Alan Cox <alan redhat com>]

Several people reported problems with programs like finger showing non
existant sessions as well as showing random idle times for remote X sessions.
This update should fix those problems with finger. I've prepared another
patch for 'w' which will hopefully follow as an update if the finger update
works.

Note: There is still another unrelated bug after 999 ssh login sessions where
sshd itself begins mishandling utmp.
