WTF?

Why are you reencoding the commits on output in fast-export?
Why aren't you dumping them raw to the stream?  fast-import takes
them raw.  Oh, it doesn't have a way to set the encoding header.
DOH.

I think this should be prefixed by fast-import patch to teach it
something like "encoding N" as a subcommand of commit, so that you
can feed data in a non UTF-8 encoding and get it to include the
proper encoding header in the commit object it creates.  That way
a pipeline like the above really does create a duplicate repository,
with the same commit SHA-1s, even if the commits weren't in UTF-8.
