YuKu's promised screenshot revealed the real section-6 chaos: the live
line 'block + msg + current package' is longer than 80 columns, so
every redraw WRAPPED to a new line instead of overwriting — the screen
filled with duplicate partial progress lines.
The line is now composed once and clamped to $(tput cols) - 2 with an
ASCII '..' tail. 80-col pty run: zero wrapped live lines (the only
>82-char output left is plain-mode dnf, unchanged by design).
