      4  * Tests for the parser symbol psym_if_expr_stmt_else, which represents the
      5  * parser state after reading the keyword 'if', the controlling expression,
      6  * the statement of the 'then' branch and the keyword 'else'.
      7  *
      8  * If the next token is an 'if', the formatting depends on the option '-ei' or
      9  * '-nei'.  Any other lookahead token completes the 'if' statement.
