print to the terminal in zle

[Stephane Chazelas <stephane.chazelas@gmail.com>]

Hiya,

recently, Debian broke some of my scripts using ZLE in `zsh -i` by adding:

        function zle-line-init () {
            emulate -L zsh
            printf '%s' ${terminfo[smkx]}
        }

To /etc/zsh/zshrc

That smkx  escape sequence is printed to stdout instead of the terminal.

What would be the correct way to do it?

Doing `printf > /dev/tty` would probably do it but it would be
better I think to be able to write to the fd that zsh currently
has opened to the terminal (usually 10 if it  was free upon zsh
startup).

is there a way to do that?

Or an alternative way to set smkx on ZLE init and rmks  on
zle-finish?
