>Description:
	Several times, i was catched by fact that if strncasecmp() is
	called with len == 0, it would return success. It should be noted
	in manpage, even through it's obvious.
>How-To-Repeat:
	do something like
	if (strncasecmp(prefix, other, strlen(prefix)) == 0)
		printf("other begins with prefix\n");
	and wonder why it works for empty prefix too.
>Fix:
	Add something like to strncasecmp() description:
	Note: if len is equal to zero, strncasecmp() returns sucess
	(i.e. 0) for any two compared strings.
