N3092 16[cpp]/4: "The only white-space characters that shall appear between
preprocessing tokens within a preprocessing directive (from just after the
introducing # preprocessing token through just before the terminating
new-line character) are space and horizontal-tab (including spaces that have
replaced comments or possibly other white-space characters in translation
phase 3)."

N3092 16.3[cpp.replace]/3: "There shall be white-space between the
identifier and the replacement list in the definition of an object-like
macro."

If the replacement list consists of no tokens, this nevertheless requires
space and/or horizontal-tab white-space between the identifier and the
terminating new-line, right?

Doesn't that just mean there's no replacement list, so no white space
is needed?
