3>log.txt opened nothing and 1>&3 was ignored, so output meant for a log went to the console, and the usual swap
3>&1 1>&2 2>&3 left the handles as they were. Handles 3 to 9 now live beside the standard three: a redirection opens
them, n>&m copies whichever one m is at that point, and copying a handle that nothing opened fails the command with
the message cmd gives. Programs started from cmd still get only the standard three.

AI-Scope: Wrote cmd's parser, IF, FOR, CALL and SETLOCAL, the built-in commands, the prompt's line editor and the batch-file test from Microsoft's public cmd documentation.
A console program started from a terminal gets it as its console without --stdio=inherit. CreateProcess runs .bat and .cmd
files through cmd /c, as Windows does. The console code pages start as UTF-8, since Raven has no table for code page 437.
