I assume you are referring to APSW here.  Blob is supposed to be
following *exactly* what the builtin Python file type does.  In
particular only strings (Python 2) or bytes (Python 3) are returned for
data, and I need to double check what happens once end of blob/file is
reached (empty, none etc)

BTW NULL is never returned back to Python code.  It is how a C function
using the Python API signals an error to its caller.

The code and documentation are indeed inconsistent.  Thanks for
reporting this - I will have it fixed before the end of the day.

The next APSW release will be in the next few days shortly after SQLite
3.6.15 comes out.
