The problem with this is all terminals are a bit different in generally
undetectable ways and off-by-one errors are endemic.  Zsh is
particularly sensitive as not many other tools have multiline effects
without taking over the output of the entire screen.

I think I replied to a previous report saying about the best we could
do to fix generally was add a user control, though I'm not sure what
for that would take --- it would just have to be "suck it and see"
but it's an obscure thing to have to look for.
