in our custom themes.
With zsh starting at version 5.4, when using the `prompt_opts` array,
`nopromptsp` will be set unless the array contains a `sp`. This was
introduced in zsh at
43e55a9bcd (diff-bb10d67e7a8561b66a53a805f3c77a40R233)Fixes#209
as they were only being used by gitster prompt theme and kept for
Oh-My-Zsh compatibility. The newly introduced git-info module (inspired
by the git-info Prezto function) provides a more powerful
implementation than the Oh-My-Zsh inspired git_prompt_info.
Updated gitster to use the git-info module.
