Thanks for the explanations. For me, $PREBUFFER does work:

$ print $ZSH_VERSION $ZSH_PATCHLEVEL
4.3.10 1.4705
$ cat /etc/redhat-release; rpm -qf =zsh
Fedora release 12 (Constantine)
zsh-4.3.10-4.fc12.x86_64

$ functions TRAPINT
TRAPINT () {
        zle && [[ $HISTNO -eq $HISTCMD ]] && print -s -r -- "$PREBUFFER$BUFFER"
        echo "prebuffer: '$PREBUFFER'"
        return $1
}

$ for i in *
for> do
for> echo<INTERRUPT>prebuffer: 'for i in *
do
'

$

But the problem I have now is that when I now go up in the history, the
last command I see is

	for i in *
	do

which is what standard zsh saved - without the last partial line - and when I
go up another command in history I see

	for i in *
	do
	echo

which is what my code saved. I wished there was a way not to save that
shorter version, with only the accepted lines.

Of course, it's not so terrible as it is - I just wondered if there's a
way to do it better. Usually when I interrupt a multi-line command entry,
it's not because I'm not pleased with the last line I typed (if this was
the case, I could have just backspaced...), but rather, I'm not pleased
with the whole thing. So I want to save the whole thing (including the
last line I'm editing), and go to edit it later if I wish.
