formatter print_* commands should pass kwargs

Allows giving a file= argument for better testing (maybe,
unimplemented) or passing a stringio

Maybe would be better to just have these functions return a string,
but then there would be no possibility ever to stream output, and the
print statement would have to be elsewhere (probs in the individual
command functions)
