This option is useful for working with files that have special characters like newlines embedded in them. It makes it it possible to pass this output to other downstream commands that can process null terminated strings, e.g. "parallel --null ..." Added option string, new function MFU_PRED_PRINT0() and argument parsing to select this feature.
The null character wasn't showing up in the output because it was included in the printf string format. Had to add it as an explicit character to get \0 to be present in the output.
