I’ve wired up `SpaceInComments` per your struct.

At the moment, `AfterOpeningParamComment` defaults to `Leave`, which means parameter comments fall back to whatever AfterOpeningComment specifies—e.g., if the general option is `Always`, we still insert the leading space in `/*param=*/`, and if it’s `Never`, we remove it. Setting `AfterOpeningParamComment` to `Always` or `Never` overrides that fallback.

Is that the interaction you were expecting, or should `Leave` on the parameter knob preserve the existing spacing even when the general control is driving changes?
