_ zsh の prompt に VCS info を表示する, 2020版

いや, 単に zsh-async に感動したダケなんですけどね.

## VCS info
ps_vcs_info=''
if [[ -n $(echo ${^fpath}/vcs_info(N)) && \
          x"$_PR_GIT_UPDATE_" = x"0" ]] ; then
    autoload -Uz vcs_info
    zstyle ':vcs_info:*' enable git hg svn bzr
    zstyle ':vcs_info:*' formats '%s:%b'
    zstyle ':vcs_info:*' actionformats '%s:%b|%a'
    zstyle ':vcs_info:(svn|bzr)' branchformat '%b:r%r'
    zstyle ':vcs_info:bzr:*' use-simple true
    zstyle ':vcs_info:git:*' check-for-changes true
    zstyle ':vcs_info:git:*' stagedstr "%B%F{yellow}"
    zstyle ':vcs_info:git:*' unstagedstr "%B%F{red}"
    zstyle ':vcs_info:git:*' formats '%B%F{green}%c%u%s:%b'
    zstyle ':vcs_info:git:*' actionformats '%B%c%u%F{red}%s:%b'
    function prompt_vcs_info(){
        LANG=C vcs_info "$@"
        if [[ -n "$vcs_info_msg_0_" ]]; then
            ps_vcs_info="%b%f[$vcs_info_msg_0_%b%f]"
        else
            ps_vcs_info=''
