For the record:

Markus has posed patches of this nature many times over the past weeks
and months. They are not fixing bugs - there is no user visible problem.
And moreover they move the code away from the preferred style -
avoiding unnecessary checks around code that can handle NULL values.

Markus, please stop posting patches of this nature.
