repo.index.add() method attempts to chmod files which it should not #2021
Description
The behavior of the repo.index.add() method behaves differently than the CLI equivalent git add:
0$ git add *
0$ python3 -c 'import git; git.Repo.init().git.add("*")'
0$ python3 -c 'import git; git.Repo.init().index.add("*")'

I don't see any reason that the python-native methods should be doing anything different than what the CLI does.
