Why did you expect `delete-selection-mode' to kill rather than delete?

I asked on stack exchange for how to change the behaviour and someone suggested it was a bug.  I figured delete-selection-mode was less of a mouthful than maybe-delete-or-kill-selection-mode ;)

The critical code lines were was also ambiguous and beyond my powers of comprehension:

(put 'self-insert-command 'delete-selection

     (lambda ()

       (not (run-hook-with-args-until-success

             'self-insert-uses-region-functions))))

Thanks for confirming the default behaviour.  On changing to kill rather than delete with:

(put 'self-insert-command 'delete-selection 'kill)

I get no self-inserted key, and an extra blank item in the kill ring.

Regardless, why don't we call this a hack and not a bug.
