//! Port of `_command` from `Completion/Zsh/Command/_command`.
//!
//! Full upstream body (master, 7 lines verbatim):
//! ```text
//! sh:1  #compdef command
//! sh:2
//! sh:3  _arguments -S : \
//! sh:4    '-v[indicate result of command search]:*:command:_path_commands' \
//! sh:5    '-V[show result of command search in verbose form]:*:command:_path_commands' \
//! sh:6    '(-)-p[use default PATH to find command]' \
//! sh:7    '*:: : _normal -p $service'
//! ```
//!
//! zsh 5.9.1/5.9.2 had a bare `_arguments \` at sh:3; master passes `-S :`
//! so a `--` ends the option words. A drop-in run as `zsh` keeps 5.9.2's.
