I don't think that isatty() should be the sole determining factor. I'd
rather see it used to select a default format but to allow the choice
to be overridden.

E.g. you might want the "pretty" format to still be used if the output
is piped through more, less, pr, etc, but piping will result in stdout
being a pipe rather than a tty.
