>Description:
calendar segfaults on the following input line:
Monday 1500-1600 something
The backtrace is:
(gdb) r -f ~/calendar.test
Starting program: /usr/src/usr.bin/calendar/calendar -f ~/calendar.test

Program received signal SIGSEGV, Segmentation fault.
0x0000000000401cc3 in isnow (endp=0x7f7ffda0906c "1600 something")
    at calendar.c:297
297             day = cumdays[month] + day;
(gdb) bt
#0  0x0000000000401cc3 in isnow (endp=0x7f7ffda0906c "1600 something")

(gdb) p month
$1 = 1500

This is a regression -- it worked in 2.0.
