Tiny redraw issue in alt-x prompt

Tiny redraw issue in alt-x prompt

[Mikael Magnusson]

To reproduce:
zsh -f
<alt-x>
a<tab><continue typing>

will produce the following three "screenshots"
1)
%
execute: _
2)
%
execute: a_
accept-and-hold                accept-line-and-down-history
accept-and-infer-next-history  argument-base
accept-and-menu-complete       auto-suffix-remove
accept-line                    auto-suffix-retain
3)
%
execute: accept-and-_
                ccept-and-hold
accept-line-and-down-history
accept-and-infer-next-history  argument-base
accept-and-menu-complete       auto-suffix-remove
accept-line                    auto-suffix-retain

the spaces before ccept-and-hold are such that the actual word remains
in the same place in the terminal due to the linebreak, so it actually
looks like this:
%
execute: accept-and_
 ccept-and-hold                accept-line-and-down-history
accept-and-infer-next-history  argument-base
accept-and-menu-complete       auto-suffix-remove
accept-line                    auto-suffix-retain
