Re: builtin echo command redirection misbehaves in detached scripts when terminal is closed

[Pierre-Philippe Coupard]

The change is far from trivial or harmless, if it was intended. I had to 
rebuild a custom server I run in a hurry because it was flooding an IRC 
channel with log lines a backend bash script sent to stderr. And I can 
think of plenty of ways to trash files with this bug.

Anyway, thanks a lot Stéphane and Andreas for testing this!
