That's caused by <http://www.spinics.net/lists/dash/msg00942.html>, not 
by Arch. It's scary that this has gone totally unnoticed for more than a

While the original code implementing the echo command was overly 
complicated, the simplified version does not do the right thing, as you 
noticed.

Here's another attempt at a simplified implementation.
