newsyslog no longer sets up a weekly command to tar up
/root/.history-save and removes /etc/newsyslog.weekly/audit if it
exists.  We're no longer using per-user history files and we're
letting bash handle managing the length of the history file.

newsyslog now creates btmp and wtmp writable by group utmp, matching
the operating system defaults.

newsyslog no longer attempts to clean up sysklogd cron jobs or remove
the old /etc/newsyslog.daily/syslog file installed by ancient versions
of stanford-server.

General coding style cleanup.
