History

Modified in 8.1.20 (👉fb85149) shell/1,2: if the `user_input`, `user_output` and `user_error` streams are connected to a file descriptors, `dup()` these to the process' standard streams. This allows running shell commands and get the output in the expected place using the upcoming embedded SSH server.
