Missing documentation for special character: Background about tbot

[Rahix]

Hi!

I think I've left it out of documentation because it has a few nasty side-effects. If a program in the background still outputs to the console, this will silently break things. Ideally, a proper Background special symbol would always redirect output to prevent all console clobbering. E.g.

# Automatically adds redirects to /dev/null
m.exec0("python", "-m", "http.server", linux.Background)

# Redirect stdout
m.exec0("python", "-m", "http.server", linux.Background(stdout="/tmp/http.log"))

# Redirect stdout & stderr
m.exec0("python", "-m", "http.server", linux.Background(stdout="/tmp/http.log", stderr="/tmp/http-error.log"))

But this, of course, needs to be implemented first ...

Finally got around to adding this: https://tbot.tools/modules/machine_linux.html#tbot.machine.linux.Background
