Use case:
1. Deploy from source to target a changed Workflow (from active to deactivated)
2. Target already has all of the workflow's referenced components (fields used in filter criteria, fields used in Field Update)

Analyzer will tell you "Add the following to the deployment" and something that looks like:

Deploy All
- object.WfName
-- object and its subcomponents
-- object and its subcomponents
-- object and its subcomponents

Since the object is already in the target as are the subcomponents, this message is alarmingly misleading and could inadvertently lead to deploying an object not yet ready.

The above message should appear ONLY if the workflow references components that are not in target nor are in the deployment package
