MPW Shell 0.4
# set X "`echo a`"
    echo a
  set X "a "

Carriage returns are converted to spaces in embedded commands. In bash, all extra trailing spaces are stripped. I'll verify that's what MPW does and update it.

Thanks.

	std::transform(tmp.begin(), tmp.end(), tmp.begin(), [](uint8_t x){
	if (x == '\r' \|\| x == '\n') x = ' ';
	return x;
	});

The embedded command adds an extra space.
