> Treatment of content from standard in by - and /dev/stdin differs when format
> is not specified.
> Using -, non RDF/XML content is silently ignored. Specifying -n gets it
> treated correctly.

> -n with /dev/stdin works, too. Using /dev/stdin with no format option blows
> up, though. (It's not silently ignored like - was)
