Range information after filename doesn't seem to be the best idea. If 
optional, then it's wrong, because it can't be told if it's there or 
if it's part of filename. If mandatory, then it would work and only 
doesn't look nice.

Rather than inventing new custom reply format, wouldn't it be better 
to adopt MLSx style? It's simple, readable, extensible, ...

E.g.:

   S> 213 Hash.SHA-256=f0ad929cd...;Range=802816-1000000; filename.ext

And the relation between HASH and MLSx doesn't necessarily have to 
end with this. Hash as optional MLSx fact would be nice answer to 
already requested hashes for multiple files at the same time.
