I see now. I have similar annoyance with Git -- which uses ^H (or was it CR?) 
to over-write line of text when indicating pull progress (1% ^H^H2% ^H^H^3% 
etc.etc.).

I believe there's no direct replacement, but let's ask the nice folks on 
9fans@9fans.net -- I'm cross-posting this message.

I'm far from an expert here, but I believe the underlying model here is
that a line at a time in/out of the subordinate command (in this case
picolisp) is the smallest unit of exchange to Acme.

Tell me some details about the environment where you're running
picolisp/acme (OS/architecture/versions of picolisp and acme) and I can try
this out on my side.
