Bash Version: 3.0
Patch Level: 16
Release Status: release

Description:
        The bindings for keys C-w and C-h can't be changed or
        removed by bind or inputrc.  Bindings for some other key
        sequences still work properly.

Repeat-By:
        bind '"\C-w": dump-variables'
        then type ^W -- no dump.
        Verify with bind -P | grep C-w that the binding didn't change.

        bind -r '"\C-w"'
        then type bind -P | grep C-w
        see that the binding wasn't removed.

        Putting the bindings in .inputrc also fails.

This worked in bash 2.05a and bash 2.05b, but fails in 3.0.
