Enum Shell 

pub enum Shell {
    Bash,
    Zsh,
    Fish,
    Powershell,
}

The shells headwater completions writes a script for.

Four, where clap_complete offers five

clap_complete::Shell carries Elvish as well. It is not here, and the reason is spec 6’s own rule about the CLI grammar block: a name that block declares either runs or states its wait. Clause 8 of #321 names four shells, the grammar block names the same four, and each of the four is a script this repository has run rather than a name passed through to a generator. A fifth would be a name in the grammar that nothing here has ever executed.

A name outside the four is refused by clap with the four printed, because this is the value parser rather than a match arm underneath one.

Variants
