There are two points which support Ulrich's and my interpretation of
C99 on this issue:
  - Clause 3 of 5.2.1 talks about the basic character set only,
    meaning that all decimal digits are elements of the basic character set
    and thus not "extended characters".
  - The word "digits" is in an italic font, and an italic font in this
    document usually means "here is a new term that is being defined".
    This is the term that is then referred to in section 7.25.2.1.5.
