Description

Consider [cpp.stringize]

Let the stringizing argument be the preprocessing token sequence for the corresponding argument with placemarker tokens removed. Each occurrence of whitespace between the stringizing argument's preprocessing tokens becomes a single space character in the character string literal.

Since whitespace is not a preprocessing token, the preprocessing token sequence should only consist of each preprocessing token that appears in the corresponding argument(i.e, a stringizing-argument does not contain whitespaces). This point is also highlighted in the answer of this issue
