- Implement possible fix for git 2.17 issue with string case. Suggested
a better fix for later.
- Implemented python stashed support. Is this in Haskell version? Will
have to check.
- Reorganized zshrc.sh to be a bit clearer. Few changes such as theme
and formatting to align with bash-git-prompt.
- Small tidy up to the README.

- All commands checked for bad return. No longer need stderr connected.

- Issue was a simple typo in zshrc.sh
- Revert gitstatus.py to printing on line.

- Really need to get some tests to help cover this.

- Simple logic problem was the root.
- Update gitignore, mainly usual python test dirs and stack's dirs.

- Will check for style issues and run unit tests.

- FIX: Prompt was not showing when detached HEAD.
- BUG: pytest fails from tox, will investigate.

- Tox env has no configured user information.
- Generate work folders from tempfile.

- Test on 2.7, 3.4, 3.5, 3.6.
- 3.2, 3.3 should work but getting excessive.
- 2.6.x and 3.1.x are unsupported based on code at this time.

- Simple suffix to branch name. Will appear if detached is local too.
- Travis locked to master build.

 - Remove all need for commands except for: git status --branch
 --porcelain
 - Parse porcelain capture status for repo's staged/unstaged changes.
 - Parse porcelain capture for difference from remote if set.
 - Fetch stash number and hash directly from files in .git
 - Now parsing upstream name, can be set on prompt at later date when
 changes facilitate.

- Notes for future improvements.

- When no stdin detected, fallback to running own command.

- Script aware now if in worktree or not, no visual difference in prompt
at this point.

- Typo in zshrc.sh

- Ensure consistent colouring by using resets around output.

- Increase function purity by reducing global usage.

- Overhaul of tests. Clearly separate functional and integration tests.
- git_paths now resolves possible merge_file and rebase_dir, not
guaranteed to exist.
- Update README to show all possible branch states, including merging and
rebase now added.

- Clarify diverge test, different numbers.
