So the problem here appears to be if you have:

• a templateUrl+replace directive (info) inside an async transclusion directive (trans)
• and the info directive also has a transclusion-based directive at its root (transSync)

In this scenario, the transcludeFn is not passed to the transSync nodeLinkFn at link time.

(The trans directive is simulating what ng-if does, which is call its transludeFn during a subsequent digest if its value evaluates to true)

If the trans directive is not async then the transcludeFn does get passed.

In debugging you can see that the delayedNodeLinkFn is not passing the transcludeFn down to the afterTemplateNodeLinkFn

LGTM --- might be good to clean up some of the empty lines that the diff adds but it's not that big a deal.
