/*
 * 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
 *	FreeBSD r309342

/*
 * Before 2023-05-11, the two 'if' statements below exercised two different
 * code paths, even though they look very similar.
