Problems with echo -e "\xNNN"

Hi there,

I just noticed a problem with "echo" in BusyBox v0.61.pre. 
Unfortunatly I can't test it with a newer version. So maybe someone 
could verify this on a 1.0pre:

I did:

~ # echo -e "\061"
1
~ # echo -e "\x31"
\x31

So it looks like "\xNNN" is not working.

Thanks,

Steven
