Some of these handled multiline prompts but not multiline command lines. We
first need to move the cursor to the end of the commandline, then we can
print a message. Finally, we need to move the cursor back to where it was.
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.
As explained in the parent commit, if we print things to the command line,
we move the cursor down before redrawing a multi-line prompt. This is a
workaround to avoid erasing what we printed.
We forgot to do add this workaround to fish_job_summary. When running
`sleep 1 &` with a multiline prompt, the job exit notification is immediately
overwritten (most of the time). This can be observed consistently on Linux
by waiting before redrawing:

Move the cursor down to work around this. In future, we could avoid calling
fish_prompt. Also, this solution add an extra blank lines before the next
prompt. With a real fix, we could get rid of that. Even worse, sometimes
there are two blank lines instead of one (for a two-line prompt).
Fixes#8817
We don't need to call it if a job was stopped, because in that case
read_i() will fire fish_prompt already, because the newly stopped job
was probably a foreground job.
Fixes#1018
The default implementation will not print any output in that case, but this provides users with additional flexibility when it comes to customising the shell's behaviour.
This allows users to customise the behaviour of the shell by redefining the function. This is similar to how fish_title or fish_greeting behave, where the default implementation can be easily overridden.
The function receives as arguments the job id, command line, signal name and signal description.
