I agree that an output mode that claims to be --porcelain should
produce output that is machine-parseable without ambiguity.

The usual practice is to use quote_c_style() for output without
"-z", and with "-z", just use the NUL as the termination character,
as you shouldn't be listing strings with embedded NUL.
