Yep, I just tried that too. It catches that. It also catches
the in/output of subshells - like, say, kicking off sh interactively.
Similarly, if you're running text-based emacs, it catches the output
of spawning to a shell from there and doing things.
The only restriction I have run into so far, it that - for obvious
reasons - sudo cannot see into what you're doing if you kick off
an X application like xterm or graphical emacs, for instance.
