C++ parser: Should we get rid of cp_parser_declarator_id?

[Volker Reichelt]

The C++ parser contains the static function
  cp_parser_declarator_id (cp_parser* parser)
which consists of a lot of comments and a single statement

  return cp_parser_id_expression (parser,
                                  /*template_keyword_p=*/false,
                                  /*check_dependency_p=*/false,
                                  /*template_p=*/NULL,
                                  /*declarator_p=*/true);

and which has a single caller.

Shouldn't we fold cp_parser_declarator_id into the caller and call
cp_parser_id_expression directly?
But what about the comments then? (Are they still accurate, btw.?)
Or should we leave the function intact just to preserve the comments?
