bug - git version 2.20.1.windows.1

[Krzysztof Sobierajczyk <sobierajczyk.krzysztof@gmail.com>]

for example, I've created a simple repository. Containing two files
('to rename.txt' and 'to remove.txt'). I wanted to prepare for the
index changing the name of the first file and deleting the second
file. what git shows you looks wrong. Please check the four
instructions

$ git add .
$ git commit -m " first commit"
$ git mv to\ rename.txt new\ name.txt
$ git rm to\ remove.txt





SAMPLE REPOSITORY AND TEST

Untracked files:
  (use "git add <file>..." to include in what will be committed)

        to remove.txt
        to rename.txt

nothing added to commit but untracked files present (use "git add" to track)

Changes to be committed:
  (use "git rm --cached <file>..." to unstage)
