Rewritten URLs: (single and double) quotes not rewritten raise MalformedPathException

(Single or double) quotes in the name of new folders and documents must be rewritten.

Steps:
1. log in to CMS quickstart as 'admin'
2. click "To the documents', then demosite and open the commands menu, select "Add new folder..."
3. name it 'newf' or "newf" (including the quotes)
4. notice that the URL name matches exactly the Name
5. press OK

Exp: system should carry on and perform the task OR provide pertinent feedback as to why it can't

Act: a message pops up saying "An error occur, please retry.". An exception is raised as follows,

23.01.2010 11:23:18 ERROR [org.hippoecm.addon.workflow.CompatibilityWorkflowPlugin$WorkflowAction$WorkflowDialog.onOk():201] Error during workflow execution
javax.jcr.RepositoryException: failed to resolve path 'newf' relative to node /content/documents/demosite: ''newf'' is not a valid path. ''' not a valid name character.: ''newf'' is not a valid path. ''' not a valid name character.

Note: the error is reported accurately, and I think that the quotes should be rewritten upfront.
