cal tool doesn't work for some arguments

[Fi Stach]

Extending the issue #908233:

cal -w
cal -e
cal -J

also don't work, cal prints the usage info instead of required output.

Separate thing: month names printed by cal [year] in Polish language are incorrect. They should be the same as for example in java

import java.time.Month
import java.time.format.TextStyle

for (int i=1; i<13; i++) {
    System.out.println(Month.of(i).getDisplayName(TextStyle.FULL_STANDALONE, Locale.forLanguageTag("pl-PL")));
}

so
styczeń, luty, marzec, kwiecień, maj, czerwiec, lipiec, sierpień, wrzesień, październik, listopad, grudzień.

Instead they are Stycznia, Lutego, Marca, ... so they are in the inflected form.
