bindings: hard-bind <Ctrl+Shift+Delete> to 'cutwordleft' 

On FreeBSD and NetBSD (when reached through ssh from a Linux machine)
this has the absurd effect of making <Ctrl+Backspace> do a 'cutwordleft'
by default, out of the box, without needing any rebindings.  Weird, but
wonderful, because the ideal behavior.

Also ensure that <Shift+Delete> always does a Backspace.

This makes that we have the following set of "congruent" keys:

  <Tab> moves text to the right,
  <Shift+Tab> moves text to the left,
  <Delete> "eats" a character to the right,
  <Shift+Delete> "eats" a character to the left,
  <Ctrl+Delete> "eats" a word to the right,
  <Shift+Ctrl+Delete> "eats" a word to the left.
