     I think that the text is intended to mean the same thing as the BNF, but
     is a little sloppy. It doesn't really mean anywhere in a number except
     the first character, it means anywhere in a numeric field of a number.
     
     So, anywhere in the first token, the size constant (which is a number,
     though not the grammar element "number") or the third token, the unsigned
     number that gives the value (again, a number, but not the grammar element
     "number"), but not as the first character of either.
     
     The whole section is rather sloppy in its use of "number" to mean multiple
     different things.
