CLI autocompletion false-positive when the group name has spacing

[yuan-y-chang]

Reproduce

Environment: zsh, Ubuntu

When we have

[doc: "Prepare environment"]
[group: "integration test"]
prepare-env:

just --list shows

> just --list
Available recipes:

[integration test]
prepare-env # Prepare environment

and type just <tab><tab> on the terminal:

> just \[integration
[integration                                            -- Args: test]
prepare-env                                             -- Args: # Prepare environment

How to avoid it

Use other characters instead of spacing.

[doc: "Prepare environment"]
[group: "integration-test"]
prepare-env:

type just <tab><tab>

> just prepare-env
prepare-env                                             -- Args: # Prepare environment
