The most configurable way is to use the special widget, the same one
that you've now got bind to the usual backward-kill-word functions, but
under a different name.  Then you can set a special style for the
behaviour.  Then you have all the same possibilities as the widget
functions at your fingertips, without having to redefine any functions.


# Create widget backward-kill-space-word, using the generic
# backward-kill-word widget function.
zle -N backward-kill-space-word backward-kill-word-match
# Tell it to use "space" style for words.
zstyle ':zle:backward-kill-space-word:*' word-style space
# Bind it.
bindkey '^W' backward-kill-space-word


The zshcontrib manual lists the various styles.
