Re: [PATCH] Avoid spurious error messages on error mistakes.

Prior to that, if the user chose "squash" as a first action, the stderr
looked like:

    grep: /home/madcoder/dev/scm/git/.git/rebase-merge/done: No such file or directory
    Cannot 'squash' without a previous commit

Now the first line is gone.
