By the way, a little known Linux trick is that if you can read from 
stderr too. So if you want to have an interactive filter in a pipeline, 
that reads from stdin and writes to stdout, you can have it do all of 
it's interaction (both ways) on stderr to read from the terminal.

That's how `vim -' works
