I'm not sure how this defeats my expectation though?  I want the SPC to
be deleted and it does it do it when the buffer contains "b b" with the
point over SPC but it fails to do so when the buffer contains "ரு b"
instead.  I was under the impression that I could safely rebind C-d to
delete-forward-char.
