The WS cleanup plugin is really great for removing everything except the .git directories from the workspace. However, it leaves around a ton of empty directories when this is done.

For example, we use the Exclusion pattern:
**/.git/**
to do this.

It would be very useful if there was an option to recursively (going up) remove any directories emptied by the WS cleanup plugin. (ie if a directory was empty previously, it would not remove it).
