Full name of submitter: Fraser Gordon

Reference: [lex.ccon] hexadecimal-escape-sequence

Link to reflector thread: https://lists.isocpp.org/std-proposals/2023/01/5532.php

Issue description:

The hexadecimal-escape-sequence rule matches text of the form \x{20}20 as an escape sequence due to its recursive definition.

Suggested resolution:

hexadecimal-escape-sequence:
\x simple-hexadecimal-digit-sequence
\x{ simple-hexadecimal-digit-sequence }
