allow saving an editor file as the current one (bug #40759) * file-editor-tab.cc (handle_save_file_as_answer): just save the file if the selected file name is the same as the current file name (handle_save_file_as_answer_close): removed the case that the selected file name is the same as the current one because the latter is not valid here (message_duplicate_file_name): removed message since not needed anymore * file-editor-tab.h: removed message_duplicate_file_name
