[bug?] git-diff shows nothing when project root is not a git repo.

[trusktr]

I have a project where the root contains two git repositories, but the root of the project is not itself a git repo:

project
  repo1
  repo2

When I edit files in either of repo1 or repo2, the editor does not show any changes in those files.

Seems like git-diff only works when the project root is a git repo, otherwise it does nothing.

I have various projects like this, where the root is not a repo, so the package unfortunately does nothing in those cases.
