So you're assuming unix-word-rubout in bash? (The usual bash/readline
rules for words are to use alphanumerics only, but the default ^w
binding does what you show.)
As you're using zsh 4.1.1, you have an easy solution: redefine
backward-kill-word to the Swiss-army-knife function variant with
`-match' appended, and set the style to use whitespace word boundaries:
bindkey '^w' backward-kill-word # as before
autoload -U backward-kill-word-match
zle -N backward-kill-word backward-kill-word-match
zstyle ':zle:backward-kill-word' word-style whitespace
See the zshcontrib manual for more on these functions, implemented by
match-words-by-style (and not match-word-by-style, hence the following
patch). If you want all functions to use this behaviour, you can use
select-word-style (which you can bind to a keystroke for instant
control) instead of setting the style yourself.
