MORE does read commands from stdin about geckos-v2 HOT 5 CLOSED

Some background information:

• Your terminal is not a terminal: https://lucasfcosta.com/2019/04/07/streams-introduction.html
• TTY demystified: https://www.linusakesson.net/programming/tty/

from geckos-v2.

So, how to fix this? I could introduce a "STDCIN" or "STDEIN" (for console in, or error in resp.) as fourth std stream to a task. It would be inherited from the parent, so FORK would not necessarily need to be modified. MORE could read from it to show the next page.

But then, how to run a program on a new "controlling" terminal? In unix, that is something that "init" does (or today something that that creates a pty), not something a shell does. Maybe introduce a FORK variant for PTY?

A STDERR/STDCIN to communicate with the terminal would be a good thing e.g. when thinking about changing baud rates on a terminal, or get info on screen geo changes (e.g. window resize). But then how to make sure multiple programs on the same controlling terminal don't confuse each other?

fix MORE:

• introduce STDCIN
  -- per process, inherited from parent
  -- DUP can change it, to be used in
  -- TTY command to switch to another console (fork child on new console and terminate)

from geckos-v2.

Reopened, as "tty" command is missing to actually run a command on a different console - including the remapping of STDCIN

Note: "MORE" also injects empty lines,which it should not do, when it prints its continuation message
