This patch adds a -f fil flag to last. The flag will cause l
last to use fil as the wtmp file, instead of the default /usr/adm/wtmp.
Possible problem: user can specify any file for the wtmp file.
If the file given is not in the same format as a real wtmp file, last
will return some really odd results.
