I should be clearer about this in my description. Of course, both
approaches work here but this won't output a NUL character if the test
fails, which could be considered as a binary file to diff.

Actually, this is something that Junio saw in a previous patch, and this
was his comment about it [1]:

But anyway, I'll make it clear in my next version.

Thanks!
