+ An action routine can, when needed, update the out_name & for_name

+ usually it just updates the output_name and for_name so should free
+ them before replacing them. The get_output_file_with_visibility
+ function creates an outf_p only once per each output_name, so it
+ scans the output_files list for previously seen output file names.
