[PATCH] Improved error message from git-rebase

If the index wasn't clean, git-rebase would simply show the output from
git-diff-index with no further comment to the user.

git-rebase sometimes fails without giving a useful error message.  Try
this:

  $ touch asdf
  $ git add asdf
  $ git rebase origin/master
  A       asdf
  $ 

diff --git a/git-rebase.sh b/git-rebase.sh
