New issue 297: Git 2.13 warns: fatal: --local can only be used inside a git repository

Mads Kiilerich:

Running tests with Git 2.13.0 gives a warning:
```
fatal: BUG: setup_git_env called without repository
```


2.13.5 gives:
```
fatal: --local can only be used inside a git repository
```

I don't know if it has other implications.
