We use --porcelain given that this spits out the results
in an easy-to-parse format for scripts and will remain stable
across git versions and regardless of user configuration.
We will use this later.

+ For interpretation of the porcelain output refer to
+ the git status(1) man page. In summary the first column is the
+ index state, the second represents the working tree state and
+ the third column are files in cases of renames. This gives back
+ None in case no changes are present, otherwise it returns a list
+ of dict entries with key values: index, work_tree, and files. The
+ files are a list of all files found on that entry, in case of a rename
+ this would consist of a list of 2 files.
+
+ As an example if you had this on your git status:
+
+ R udev/foo.sh -> poo/foo.sh
+ D scripts/bar.sh
+ ?? .poo.py.swp
+
+ This would be transposed into the following dict:
+
+ results = status(tree=your_git_tree_path)
+ if not results:
+ return 0
+ for entry in results:
+ print entry
+
+ {'files': [' udev/foo.sh', 'poo/foo.sh'], 'index': 'R', 'work_tree': ' '}
+ {'files': [' scripts/bar.sh'], 'index': 'D', 'work_tree': ' '}
