Re: builtin echo command redirection misbehaves in detached scripts when

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 St├ęphane and Andreas for testing this!

Dmitry, you may find that whole thread at:
