Here is the wording in Clause 6.1.2  (you had a slight typo in the Clause ref?):

  Any identifiers that differ in a significant character are different identifiers.
  If two identifiers differ in a nonsignificant character, the behavior is undefined.

I see your point in needing to re-word that second sentence to somthing similar to:

  If two identifiers differ only in a nonsignificant character, the behavior is undefined.

I don't know if this has been fixed.
