Bug: git difftool --tool=meld -d HEAD^ lose copied file

[Kirill <ks1322@gmail.com>]

Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)

mkdir git-copy-lost
cd git-copy-lost
git init
touch file
git add file
git commit -am "message"
git rm file
git commit -am "message"
git difftool --tool=meld -d HEAD^

In meld right click on `file` in left pane and press "Copy To Right" in menu
Quit meld

ls -l

What did you expect to happen? (Expected behavior)

`file` is present in working directory

What happened instead? (Actual behavior)

`file` is absent in working directory

What's different between what you expected and what actually happened?

`file` is missing while it was copied in meld with "Copy To Right" button

Anything else you want to add:

This bug was also reported for meld but I don't think meld can do
anything with it
because copied file is being lost in temporary directory like
/tmp/git-difftool.7bOf2n/right/ created by git
