Gratuitous reformatting?
Elimination of an overly long line?
I usually try to gather any coding style, comment grammar, etc., fixes
into a single patch or two at the beginning of a series. That keeps the
substantive patches (the hardest to understand) shorter.
That's probably great advice. I can easily enough undo the change
since it does not affect the functionality of the patch. It was
made while I was doing the analysis for the patch and to make the
style better match the style used in other surrounding routines.
Thanx...

I wonder if a tail-call might not work better here.
"Tail-call"?
