lacrymology@Roller:boilerplate$ git diff
boilerplate/apps/custom_zinnia/abstract_models.py
test_project:boilerplate/apps/custom_zinnia/models/blog.py
fatal: Path 'boilerplate/apps/custom_zinnia/models/blog.py' exists,
but not 'boilerplate/apps/custom_zinnia/models/blog.py'.
Did you mean 'test_project:boilerplate/apps/custom_zinnia/models/blog.py'
aka 'test_project:./boilerplate/apps/custom_zinnia/models/blog.py'?

blog.py doesn't exist in the current branch. Current branch descends
from test_project, and abstract_models.py it's actually the same file
`git mv`'ed
