bug#16799: 24.3.50; delete-selection-mode and electric-pair-mode interaction

[Harald Hanche-Olsen <hanche@math.ntnu.no>]

Starting from emacs -Q, switch to the *scratch* buffer and run:

M-x electric-pair-mode RET
M-x delete-selection-mode RET

Place the cursor in the first line, but not at the befinning,
and type C-space C-a.

Now the region is active, and point is at the beginning of the buffer.
Type any character bound to self-insert-command.

Result:

Error in pre-command-hook (delete-selection-pre-hook): (args-out-of-range 0 1)

As a side effect, delete-selection-pre-hook is removed from
pre-command-hook, effectively disabling delete-selection-mode.
