//! What:
//!  The pathspec modes a command runs under and the sentences that name them.
//! Why:
//!  A sentence that names the wrong mode,
//! or a mode that is missed,
//! tells a person to change something that does not matter.
//!
//! In TS you'd write (pseudocode):
//! ```ts
//! // expect(modesInEffect(['--icase-pathspecs'], [])).toEqual(['--icase-pathspecs']);
//! ```
