Playing around with blacktex, am I right in thinking that it returns an error code if anything was changed? It's definitely helpful to have a way of checking whether a document is valid, but it's also useful to be able to tell the difference between a successful pass of the formatter and a failed pass of the formatter without having to dig into the error code itself. Would you consider an exit code of 0 for formats which succeeded but changed things, but a --check flag which would raise an error code if anything needed changing?
