I was responding to the statement that nobody has found a way to move
the cursor without using ncurses move().

If terminal independence is a requirement, then that's definitely the
way to go.  However, the requirement was for "linux console" only.
_If_ that requirement is correct, then I doubt the linux console codes
are going to change much over the years.  They certainly haven't in
the first 20 years.  Are there any popular terminal emulators that
won't work with the ANSI cursor-movement sequence that's used by the
Linux console?

On the third hand, given that ncurses is ubiquitous and rather small,
trying to avoid it would seem to be a false economy.
