Package: ncal Version: 12.1.7 File: /usr/share/man/man1/ncal.1.gz $ cal originally had highlighting on.
Now after installing this package, it is off. However the man page makes it seem like maybe we aren't on a terminal. But tty(1) says we are. Therefore there should be a --force-highlighting-on to test. So it turns out one needs $ ncal -C or $ ncal -b to do what $ cal used to do. Not even $ cal -C will help. By the way the man page makes it seem like we can type $ cal -b but that is an error. Because the man page assumes we typed ncal, not cal, even though both are in the SYNOPSIS.
