This was changed due to a bug report about readline not being Posix-
conformat with its ^W binding in vi insert mode. Posix specifies that
word boundaries include whitespace and punctuation. Apparently vi is
the same, but I'm not enough of a vi user to say.
The old binding (unix-word-rubout) is still there, but to avoid it being
overwritten, you need to set the readline variable `bind-tty-special-chars'
to `off'. (Since ^W is your default stty werase character, readline will
bind it to its vi-mode equivalent when that variable is enabled.)
You would have noticed the ^W binding being overwritten if you had done
a `bind -m vi-insert -p' after one of your key binding commands, but I
suppose there isn't any real reason to do that.
