- * If @c target is not a directory, we return the result of
- * calling @c apply_default_acl() on @c target. Otherwise, we convert
- * the return value of @c nftw(). If @c nftw() succeeds (returns 0),
- * then we return @c true. Otherwise, we return @c false.
- * \n\n
- * If there is an error, it will be reported via @c perror, but
- * we still return @c false.
+ * If @c nftw() fails with a serious error (returns NFTW_ERROR),
+ * then we return @c ACL_ERROR. Otherwise, we return @c ACL_SUCCESS.
