|Subject:||add space after ! operator without breaking !! secret operator|
i set -wrs="!" to make "!$var" format as "! $var", which i find to be more legible. the problem is this causes the commonly used secret operator "!!" to be reformatted as "! !". the POD mentions --tight-secret-operators, but it doesn't support "!!". if support was added, would it fix this case? or maybe the behavior could be made more generic so that the spacing is only added between operators and non-operators.
