(Path is actually r=froydnj.) Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of nsISupports. This means that nsAtom is now a better name for it than nsIAtom. MozReview-Commit-ID: 91U22X2NydP --HG-- rename : xpcom/ds/nsIAtom.h => xpcom/ds/nsAtom.h extra : rebase_source : ac3e904a21b8b48e74534fff964f1623ee937c67
