The problem is the file format, in the sense that the earlier `git cat-file commit $orig` has a human readable output which is a description of the commit header, rather than the specific binary content. I couldn't tell if the command would cope with such a human readable file.

In Christian's quick untested script he'd matched the two commands as opposites, which doesn't appear to be the case, and I'm somewhat ignorant of what hash-object is doing - I'd expect that it simply hashed the already constructed data, but my ignorance starts showing at this point ;-)
