* Changes for Issue #1058 are done in VS2017. Works fine. * calculatePopupSize use a const CommandHistory& and is called from a shared_ptr. * Some shared_ptr are converted into refrences. Better appropriated. * Add missing const stuff. Remove a comment. * cookedReadData.History() returns a ref. Callers adapted. OK.
