There may not be a single top-most one anyway (which is what that
"randomly pick" comment refers to and punts), so taking the tip
after traversal is just as good as doing it before. So this is a
good change, but it still is punting.
The "head" is used only to produce the fake "From xxxxx <datestamp>"
line to mark the output as format-patch output to /etc/magic, so it
does not make sense to do anything fancier, like erroring out with
"You specified two or more tips and we cannot pick one".
So it is a good thing to punt.
I like this simplification. Good job.
