You can also try using vi-backward-kill-word instead of backward-kill-word.

Just that one, should give what James wants.  If it doesn't, we need to

I don't think it's possible to get more primitive than up-line-or-history,
which goes up one line in a multi-line buffer or up one history entry at
the beginning of the buffer.  Unless you're looking for a primitive that
won't move out of the multi-line buffer when it reaches the top?

Meanwhile, something like this should work:

    function up-line-or-beginning-search {
	if [[ $LASTWIDGET != $WIDGET ]]
	    if [[ $BUFFER == *$'\n'* ]]
	zle .${__last_up_line:-beep}
