Good correction - `list-system-processes', not `list-processes' or
`process-list'.

[Too bad, BTW, that the doc string of `list-processes' says
"Display a list of all processes" - N.B. "ALL", not all processes
that Emacs has launched.

It mentions exclusion of certain processes, depending on argument
QUERY-ONLY and whether exited or signaled, but it does not go beyond
that to characterize which other processes might be excluded.]
