US 64-132 Annex E.4 Whitespace and pattern rules

[wg21bot]

The Unicode org has clarified that the pattern whitespace and pattern syntax rules apply to the lexing and parsing of computer languages.

Proposed change:

Replace with "UAX#31 describes how formal languages such as computer languages should describe and implement their use of whitespace and syntactically significant characters during the processes of lexing and parsing. C++ does not claim conformance with this requirement."
