 * Tests for comments after 'if (expr)' and 'else'. Before 2023-05-11, if the
 * option '-br' was given (or rather, if '-bl' was not given), indent looked
 * ahead to the following significant token to see whether it was a '{', it
 * then moved the comments after the '{'. This token swapping was error-prone
 * and thus removed.

 * See also:
 *	FreeBSD r303484
