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.

Sorry for the delay in sending v3. I've had a serious case of Lennonitis (Life is what happens to you while you're busy making other plans).
