In fact, using the `-q` switch is even (slightly) faster: a reasonable implementation of `-q` exits immediately when a match is found, while what is written here waits until all input is processed. -I haven't exhausted the problems with this function just yet. As a bonus: despite being awfully inefficient, **this function *can't even be used* in many cases for which it is designed.** You might have noticed that the order of different status bits is completely fixed by whoever wrote this function (by the way, all those `$ZSH_THEME_GIT_PROMPT_*` variables are documented nowhere, so one who wants to write a theme has to dig into the source — only to find the function useless expect for polluting the namespace). If one wants to use a different order, or put some of the bits in `RPROMPT`, one has to roll his own (or good luck parsing the output of `git_prompt_status`).

One might wonder how Prezto solves the same problem. The answer is in [`modules/git/functions/git-info`](https://github.com/sorin-ionescu/prezto/blob/08676a273eba1781ddcb63c4f89cfff9bd62eac4/modules/git/functions/git-info). The `git-info` function does more, and again in a highly modular way (without grep calls, for God's sake): status bits or their combinations are [formatted on demand with `zformat` and stored in an associative array `git_info`](https://github.com/sorin-ionescu/prezto/blob/08676a273eba1781ddcb63c4f89cfff9bd62eac4/modules/git/functions/git-info#L393-L416), where users specify format strings via `zstyle` with [thoroughly documented escape sequences](https://github.com/sorin-ionescu/prezto/tree/08676a273eba1781ddcb63c4f89cfff9bd62eac4/modules/git#theming). Very beautiful solution. |
