So I would favour this fix. I think this should be ok because we

If it isn't, you could always do
sed '1!G;h;$!d'
or
sed -n '1!G;h;$p'
instead.
Both of them are very portable indeed.
I am reminded of the last time I tried to remove a use of tac from git
(rebase -i, to be specific). I was yelled at for trying to use perl,
and "sed -ne '1!G;$p;h'" turned out to be not portable enough.
Eventually the command was re-written not to need the reversal.
Junio seems to think perl is just fine, judging by next, so I guess
I'll just give up trying to second guess what the list wants. :-/
