Subject: bug in calendar(1) on saturday.

The /sys/src/cmd/calendar.c shipped on the CD behaves as
follows.  During the week (Sunday-Thursday) it prints today's
events and tomorrow's.  On Friday, it prints events for
Friday, Saturday, and Sunday, and Monday.  On Saturday, however,
it prints events for Saturday, Sunday, and Tuesday.  This does
not agree with the man page.

A fix (pseudo-diff):

	tm = localtime(now+24*60*60);
	dates(&last, tm);
        if(tm->wday == 6){
                tm = localtime(now+2*24*60*60);
                dates(&last, tm);
        }
        if(tm->wday == 0){
                tm = localtime(now+3*24*60*60);
                dates(&last, tm);
        }

becomes

	tm = localtime(now+=24*60*60);
	dates(&last, tm);
	if(tm->wday == 6){
		tm = localtime(now+=24*60*60);
		dates(&last, tm);
	}
	if(tm->wday == 0){
		tm = localtime(now+=24*60*60);
		dates(&last, tm);
	}
