Sorry, Nick . I wasn't clear. The use case I posted was the behaviour
that I desired, which I get with the patch I posted. With your patch,
I see the same behaviour as you do. To clear things up, I would like
"empty input file" to be a warning, not an error, particularly when
the input BFD is 'binary'.

Cheers,
