The code is correct either way.

One consideration is how far a suspicious-minded programmer
must look in order to set to rest the suspicion that there
might be a memory leak.  The original code answers the
question close to the `new` operator, and that is a
goodness.  The revised code is five lines shorter, and that
too is a goodness.  Within a constructor, I think I prefer
the second goodness; but that little more than habit.

Coincidentally, in another thread Stephan Bergmann argues
<http://lists.freedesktop.org/archives/libreoffice/2011-November/020843.html>
on broader grounds against the redundant assignment.  I look
forward eagerly to that discussion.
