The "--no-index" option is meant as a bolt-on to let you use various
features of "git diff" that is missing from other people's "diff" in
a context where git does not know anything about that file.  It
should be usable even outside a git repository.

    $ git diff --no-index /dev/null new-file.txt

I do not know offhand (and didn't bother to check) if textconv
applies, though.  It does need access to a git repository as it
reads from the $GIT_DIR/config to learn what to do.
