No. If it is a valid string, *something*, i.e., an ascii character,
appears in every single position of that string. "Nothing" does not,
and can never, appear in any string.
In the string "ABC", if match("",string) were to return 1, then it's wrong,
isn't it? Because anyone can clearly see that 'A' is the first character.
And 'A' is not nothing.
