Oh, that's what I expected, don't worry about it.
I just want the code that goes in to be as clean as practical, since
it may be used for reference for future contributions.
I'm also getting more strict as time goes on as I see previous
sloppiness I accepted in the past coming back to haunt me in new
patches.

FYI, I will be off Friday-Monday. So anything you don't see by end of
today won't arrive before Tuesday - and no rush getting anything out
Monday.

For clarity: I'm all for using more parantheses than necessary where
it means avoiding needing to stop and think about operator precedence.
Ard isn't :)
But here they just don't add anything other than clutter.
