For those who are only following along on debian-user and not digging into the packages and bug reports and source code, I would simply like to add that the clear_console program shipped in Debian's package of bash is provided entirely by Debian. It does not come from the GNU project's bash at all. The comment at the top of the clear_console.c source code says: Copyright (C) 2006-2017 Canonical Ltd.
