It deals with non/inclusive. I think it means includes begin, the '[',
but not end, the ')', which is the same as [begin,end-1],
but I may have the [/] and (/) pairs backwards.
from Levente's mesage I see I'm right. the end-1 skipps the terminator
needed for a C string. So the call to getgrnam doesn't
have a valid argument. same as any C string functopn without
the proper terminator.
