[Zope-CMF] Getting state title in DCWorklow

If you're using a DCWorkflow 0.4:

Create a new variable called 'state_title' and give it a default
expression of:
	python: workflow.states[status['review_state']].title
(urgh, not pretty)
Then to retrieve it use:
	portal_workflow.getInfoFor(context, 'state_title')


Hmmm general question : any reason the Expression context is very
transition-oriented and not state-oriented ? 

In getCatalogVariablesFor and in getInfoFor we create an Expression
context which (obviously) has no transition info. It would be useful in
this situation to bind a variable like 'state', to be able to access the
current state. Should I write a patch ?

(The answer to the problem at hand would then be written
getInfoFor(context, 'state').title, assuming no permission problem.)
