I'm not quite sure what you mean by "automated patch" Greg. Manually
editing the file in emacs, then running "git format-patch", followed by
importing the patch file into alpine and sending it off surely didn't
feel "automated" ;-)
The only reason I even included the change of the return value cast was
that it was the variable I was focusing on with regards to fixing the
leak, so it felt "sufficiently related" to include in the same patch.
I certainly was not on a mission to clean up the file in general - just
fixing the leak was all that was really on the agenda.
I don't *mind* fixing up other issues in the file - sure, I can do that,
but that's an entirely different set of patches then...
