           Summary: [meta] CompositeEditCommand should not be kept alive
                    for undo and redo
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML Editing
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: rniwa at webkit.org


As discussed on webkit-dev, we should make CompositeEditCommand a temporary object that exits only to execute a command.  To reduce the memory footage and to support persistent positions, we should not keep it for undo and redo purposes.

We can instead generate a EditCommandComposition that outlives CompositeEditCommand to implement undo and redo.
