Bart pointed out when this patch appeared that terminal behaviour simply
isn't well-defined enough that all of them have consistent wrapping
behaviour, and they don't even provide enough information for the shell
to decide by itself.

About the only possibility we have to is to expand the ability to
configure the settings (we currently have ZLE_RPROMPT_INDENT, which can
be set to 1 to try to massage our way out of trouble).
