I am not opposed to an explicit "please avoid raw binary output" or
even "please make it even more machine-processable by formatting in
yaml" options.  What I was hinting at was what the default should be
for interactive use when the output goes directly to the eyes of
end-users, which is pretty much orthogonal.

Thanks.
