How do I make 'git diff --no-index' follow symlinks?

I'd like to (ab)use git's nice diff interface and make this work:

    git --no-pager diff --no-index <(echo foo) <(echo bar)

It just prints:

    -pipe:[203030063]
    +pipe:[203030065]

But I want:

    $ diff -u0 <(echo foo) <(echo bar)|tail -n 2
    -foo
    +bar

I went diving through the diff code for a bit, but couldn't find where it's stat()-ing the two files and deciding it's not going to follow symlinks.

Just having some option to follow symlinks would make this work.
