println! panics when piped into something that closes stdin early

[P-E-Meunier]

After code using println! starts working, I don't think rustaceans should have to rewrite their code using finer error control.

println!("Hello, world") should not cause a panic when piped into anything. I believe the default behaviour should be to ignore errors, people wanting finer error control can still writeln! to stdout.

I think the panicking behaviour is undesirable too, but if it's something you want control over now, you can use the try_print crate, which should do what you want.

@sfackler: thanks! I couldn't find it, sorry for the noise.
