Yeah, it doesn't mess with `$?'.

But here's something I'm finding odd. Consider this setup from "zsh -f":

[snip]
bindkey -e
PS1='%? %% '
precmd() { true }
cs () {
    zle clear-screen
    zle reset-prompt
}
zle -N cs
bindkey '^l' cs
[snap]

Then this:
0 % false
1 % (hit ^l here)
[..screen is cleared..]
0 % echo $?
1
0 %

I thought `reset-prompt' alone was enough, but it's not. Also, this only
happens, when `clear-screen' and `reset-prompt are used in a single
widget. If called separately, this doesn't happen either.
