From: Johannes Schindelin <johannes.schindelin@xxxxxx>
In the given example, `commit` cannot be `NULL` (because this is the
loop condition: if it was `NULL`, the loop body would not be entered at
all). It took this developer a moment or two to see that this is
therefore dead code.
Let's remove it, to avoid puzzling future readers.

MyFirstObjectWalk: remove unnecessary conditional statement
Our introductory documentation made me scratch my head because our
example contains dead code. I'd like to remove it lest we confuse future
contributors.
