Hi

The vi-backward-kill-word widget does not seem to respect WORDCHARS:
```
frustcomp% zsh -f
frustcomp% bindkey "^W"
"^W" vi-backward-kill-word
frustcomp% mkdir /tmp/foo_bar
frustcomp% ls /tmp/        
frustcomp% WORDCHARS='*?-.[]~=/&;!#$%^(){}<>'
frustcomp% ls /tmp/foo_bar
```
typing ^W at this point will delete 'foo_bar'.
I expect it to only delete 'bar', though, as that is what backward-kill-word does.

Is this a bug or intended?
If intended: is there a different way of adjusting the behaviour of vi-backward-kill-word?

Thank you

henk

It is intended. vi-backward-kill-word works in a vi compatible manner
both in terms of word endings but also includes refusing to delete past
the cursor position where the current insertion started. Did you want
that behaviour? Vim relaxes that unless configured otherwise.

No. But you can just bind Ctrl-W to backward-kill-word:

  bindkey '^W' backward-kill-word

Thank you. I found out that WORDCHARS actually comes from emacs. I thought it was zsh-specific. So it makes sense that these behave differently.

I did that and a few other adjustments to the keybindings now to get the behaviour I want:
```
bindkey -M vicmd 'w' forward-word
bindkey -M vicmd 'b' backward-word
bindkey -M viins '^W' backward-kill-word

# better word matching
autoload -U select-word-style
select-word-style normal
# these characters do _not_ separate words but are part of words
zstyle ':zle:*' word-chars '*?[]~;!#$%^(){}<>'
```

Now it seems to behave like I want it to.

Cheers
