apiref: Clarify documentation for unpack O format.

Browse Source 
The `O` format causes reference counts to increase, but in an error they
are not released.  Callers to unpack functions that use the `O` format
should use pointers pre-initialized to NULL so they can safely release
the reference on error.

Also corrected typo which said this was like `O` (itself).

Fixes #135
