User can copy documents to folder where she does not have write permissions

From the hippo-community mailing list ('Can copy documents to anywhere using copy workflow'):

We have restrictions in our cms that prevent editors to use workflow on certain folders/documents. Using the move or copy options in documents editors are able to copy/move these documents to places where they only have readonly rights and not editing options.

[FvL]: The workflow operation itself (#copy) invokes a different workflow method on the target folder (EmbedWorkflow#copyTo) to do the actual copying. The lookup of that separate workflow method should fail if the user does not have the necessary rights on the target folder.
