Remaining arguments and plurality

I'd like to be able to optionally control the USAGE for `.remaining` parsing to provide appropriate plurality. The screenshot below suggests that the user enters multiple location hints. They do not. With the `.remaining` parsing, the arguments become a single location hint.

_What I see:_

`USAGE: now [--time ] [ ...]`

_What I want (ideas):_

`USAGE: now [--time ] []`
`USAGE: now [--time ] <...location-hint...>`


Start by locating the `.remaining` argument parsing and the code that generates its USAGE text. Compare the current `[ ...]` output with the requested plurality forms, then verify that an optional configuration produces the intended usage wording without changing normal parsing behavior.
