incorrect range-diff output?

[Duy Nguyen <pclouds@gmail.com>]

Try

    git range-diff from...to

with those two branches from https://gitlab.com/pclouds/git.git. The
interesting part is this

      diff --git a/Documentation/gitcli.txt b/Documentation/gitcli.txt
      --- a/Documentation/gitcli.txt
    @@ -120,10 +111,11 @@

    + 

This particular hunk comes from giteveryday.txt, not gitcli.txt. And
the b/Documentation/gitcli.txt line is also missing.

I'm in the middle of some other things (and don't know range-diff that
well) so I'm just dropping a bug report here.

I've tried all 'master', 'next' and 'pu'. Same result. Tried
--no-pager too in case the pager ate something up.
