editor: resolve files copied by directory copy on-demand Before this change, the data of files brought by directory copies was resolved immediately and stored for the duration of the run. Now, only references are stored and are resolved either when opening the files or when closing the editor. It means RevisionData file data is only set once per file and only when the file has been handled. The next step is to turn RevisionData into a data store backed by the filesystem.
