Fabian Boehm 80fe0a7fcb fish_job_summary: Format message better for multiline prompts
This was supposed to be number of lines in the prompt minus 1, but
string repeat added one.

Also it triggered even in case of the stopped job message, which is
already repainted differently.

So we add it when we need to repaint ourselves.

As a bonus add a newline before in that case so the message isn't
awkwardly printed into the commandline.

Fixes #9044.

function fish_job_summary -a job_id is_foreground cmd_line signal_or_end_name signal_desc proc_pid proc_name
# job_id: ID of the job that stopped/terminated/ended.
# is_foreground: 1 if the job was running in the foreground, 0 otherwise.
# cmd_line: The command line of the job.
# signal_or_end_name: If terminated by signal, the name of the signal (e.g. SIGTERM).
# If ended, the string "ENDED". If stopped, the string "STOPPED".
# signal_desc: A description of the signal (e.g. "Polite quite request").
# Not provided if the job stopped or ended without a signal.
# If the job has more than one process:
# proc_pid: the pid of the process affected.
# proc_name: the name of that process.
# If the job has only one process, these two arguments will not be provided.
# Print nothing if we get SIGINT in the foreground process group, to avoid spamming
# obvious stuff on the console (#1119). If we get SIGINT for the foreground
# process, assume the user typed ^C and can see it working. It's possible they
# didn't, and the signal was delivered via pkill, etc., but the SIGINT/SIGTERM
# distinction is precisely to allow INT to be from a UI
# and TERM to be programmatic, so this assumption is keeping with the design of
# signals. If echoctl is on, then the terminal will have written ^C to the console.
# If off, it won't have. We don't echo ^C either way, so as to respect the user's
# preference.
