Rustyline shell autocompletion test

[tester::#WH6] Pressed “” (expecting autocomplete to “xyz_ant xyz_bee xyz_owl”)
[tester::#WH6] ^ Line does not match expected value.
[tester::#WH6] Expected: “$ xyz_”
[tester::#WH6] Received: “$ xyz_xyz_ant xyz_bee xyz_owl”

it says expecting for ‘xyz_ant xyz_bee xyz_owl‘ but then the code expects ‘$'(prompt) xyz_‘

Hey @m-epasta, looks like the completion output is being printed on the same line as the prompt. Adding a newline should fix the formatting.

To clarify, the tester expects the prompt line to remain unchanged. We definitely should improve the error message to make this clearer.
