What I know is that I learned job control very early when learning
about the shell and I use it frequently. I do expect from each shell
program to allow me to suspend it. Those running and listing programs
must be also interruptable. And I also expect to be able to stop the
output by using Control-S. This I am writing here not related to
Emacs, but to give user experience testimony. That is how I have
worked over last decades.
