Example from expr.html: Require expr "%{TIME_HOUR} -gt 9 && %{TIME_HOUR} -lt 17" fails with "unexpected $end" while Require expr %{TIME_HOUR} -gt 9 && %{TIME_HOUR} -lt 17 (ie, with quotes removed) works as expected. (Doc has since been updated.) It seems to me that the quotes should be (optionally) permitted around the expression, as this would be consistent with other modules which use the expression syntax.
Fixed on trunk in r1585609.
Thanks. You rock!
Fixed in 2.4.16
