Consider the following bash tab completions: 1. `sq <TAB>` yields a list of all subcommands and options (including `key` and `keyring`) 2. `sq k<TAB>` automatically fills in `sq key` and leaves the cursor at the end of `key` 3. `sq key<TAB><TAB>` shows nothing, if there are no local files whose names start with `key`. If one local file named `keyfoo` exists, it expands to `sq keyfoo` after the first `<TAB>`, and if two local files names `keyfoo` and `keybar` exist, it lists them both. 4. `sq key <TAB><TAB>` (note the space after `key`) shows the sub-sub-commands `adopt`, `attest-certifications`, `generate`, `help`, etc. The third item in the list above is clearly wrong. It should instead show the two options `key` and `keyring`.
