This isn't contrib/fast-import/git-p4.  Searching around, I
discovered a 2009 fork of git-p4 that is fairly active.  CC-ing
some of the names I found on github.

Here's one such repo:

    http://github.com/ermshiperete/git-p4

Git's git-p4 doesn't try to do anything special with utf-16.  It
does \r\n mangling, but not $Keyword$ removal, then just streams
it to disk however p4 sends it.  That's close to what you're
trying to do here.
