Re: Misleading documentation for git-diff-files (diff-filter)

To be clear, I don't mean to imply that diff-files should include
files that are not the index. I was trying to say that as a user, the
documentation gave me a different impression.

For background, my intent was to have a script to look for local git
repos that with unstaged changes. After some trial and error, I found
that git-ls-files gave me what I needed. However, I wanted to point
out why I initially believed git-diff-files with show "added files".
Think of this more as user feedback.
