Which part?

If you mean the svn:eol-style attribute, then it is correct that we're
not representing it in the converted repository.  We could represent
that in various ways in Git without actually altering the bytes of the
file.  Or we could alter the bytes of the file, but that would itself be
lossy.

Git doesn't represent it.

How things are checked out by Git depends on a user's local settings
(e.g. autocrlf), so there is no way we can represent things so that a
git checkout is *always* identical to an SVN checkout.  

(Is the same true of SVN?)

This is imprecisely stated.  What rules?

Again, the problem is that there's no consensus around what "correct"
means, here, and nobody has been able to articulate precisely what is
desired.
