At the first glance it may look odd, I agree. However, I tested it
and it did work for me. The fact is that "ret" is now getting passed
in by the caller, and the invocation of (in this case) lzma_alone_decoder()
was moved into the (new) caller.

If it's not that aspect of the change, I may need some more
explanation from you as to what you think is wrong.

Jan
