Fixed a bug that caused last(1) to be extremely slow in some cases, and
made other performance improving changes. This improves the performance
of last(1) by as much as 32 times in some cases, and in more typical cases
is about twice as fast.
Added a BUGS section to the manual page to describe the behavior of last(1)
when a login shell terminates abnormally (and thus doesn't write a logout
record to the wtmp file).
