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': [' .poo.py.swp'], 'index': '?', 'work_tree': '?'}
