I'd like the ability to run exa -lh --git from a directory containing multiple repositories, but which is not itself a repository. For a simple example:

cd /usr/src
git clone https://github.com/ogham/exa/
touch exa/make-it-dirty
exa -lh --git

Currently no git information is displayed since /usr/src is not a git working directory. Obviously in real life I would run this from within a folder which contains dozens of cloned repos. The important information I'd want to see for each repository is:

1. do any uncommitted non-gitignore'd changes exist
2. is the current branch a different commit from remote (only if the current branch tracks a remote branch).
3. (optional) displaying the name of currently checked out branch would be nice but not strictly needed.
