Ah, that makes sense.

awkiawki uses "dd ibs=1".  The dd from busybox, according to the (full
busybox) manual at http://www.busybox.net/downloads/BusyBox.html
doesn't accept separate ibs and obs, just bs.

The current development busybox is the same in that regard:

coreutils/dd.c?rev=HEAD&content-type=text/plain >

SUSv2, or at least what I can see at 
<URL: http://www.rdg.opengroup.org/onlinepubs/007908799/xcu/dd.html >,
which appears to be authoritative, says that ibs is a supported
operand.

So I'd say that busybox is in the wrong (at least, if it claims SUSv2
compliance); but if we want to support it anyway, we could just use
"dd bs=1" and accept that the next "cmd | getline" will be slightly
less efficient due to the multiple 1-byte writes, rather than using the
default output block size.

(Or we could note that that is a recommended change for anyone using
busybox.)
