Log Message:

        usr.bin/calendar/calendar.c: revision 1.51
Correct privilege handling problems in calendar -a (which runs as root
from /etc/daily); do not exec other programs while the real uid is
still 0.
Also, clear the supplementary groups list up front and call initgroups
when becoming another user, to avoid leaking any extra group
privileges that we might have.
And finally, don't silently ignore errors changing uid and gid; those
are serious if they happen.
