When we want to print something while the prompt is still active, we move the
cursor by printing a newline for each line in the prompt beyond the first
one. As established by 80fe0a7fc (fish_job_summary: Format message better
for multiline prompts, 2022-06-28), our use of "string repeat" actually
prints an extra newline. Let's remove it here as well.
