This paragraph ("not to aid debugging") contradicts the previous one
("For debuggers aid").

Looking at this patch and the subsequent patches, I would write the
commit message like this:

    When debugging, print the received argument at the start of the
    function instead of in the middle. This ensures that the received
    argument is printed in all code paths, and also allows a subsequent
    refactoring to not need to move the "arg" parameter.

Also change the title to "print arg earlier when debugging" or something
like that.
