Well, FWIW I've found a work-around.  Maybe it'll give someone a clue as
to how to properly solve the problem. 

I wrote a crude wrapper for isatty() which I load up with LD_PRELOAD. It
returns TRUE for stdout and stderr, otherwise it just calls the
original isatty(). And that works - output is jumbled, but not garbled
nor truncated.
