based on the Prezto git module [function](https://github.com/sorin-ionescu/prezto/blob/master/modules/git/functions/git-info) and further refactored and simplified. What changed: - Commit format only in 'detached HEAD' state, so `$(coalesce "%b" "%c")` is not needed, because you only get one of those. - Removed the `added`, `deleted`, `modified`, `renamed` and `unmerged` verbose contexts. - `git status` is only used in verbose mode. - In non-verbose mode, the `untracked` context is not available, and also untracked files are not considered for computing the `dirty` context. Using `git status` or checking for untracked files is [expensive](https://gist.github.com/sindresorhus/3898739).
