I don't think it's generally possible to figure out by how much the
cursor will move when you write a given string to TTY. If it was
possible, there would be no need for %{...%}.

An alternative would be to add another flag that says that list-colors
should be percent-expanded. Or add a new parameter that is just like
list-colors but gets percent-expanded. Unlike with raw strings,
computing the length of a string that undergoes percent-expansion is a
solved prompt.
