How to make fish shell delete words like bash does

I'm giving a second try to the fish shell. One thing that really annoys me is the "new" behaviour of Ctrl+w shortcut.

Consider following situation:

$ vim ~/.config/fish/config.fish

...having the cursor at the end of the line.

When you press Ctrl+w, following happens:

• in bash: ~/.config/fish/config.fish is deleted
• in fish: only config.fish is deleted

How can I make fish delete words that are separated by spaces only?
