Shoulds this read "-O2 or higher"?
I suppose it would be more accurate that way. I've added it to
both -Wrestrict and -fprintf-return-value in r259224.
(That's an interesting definition of typo, by the way. ;-) Not
disputing the change as such, only the ChangeLog entry.)
The typo was in the example. (Of course, I managed to introduce
a new one while fixing it...) The new sentence was incidental.

PS While looking around for other examples of "-O2 and above"
I came across a number of other similarly incomplete lists of
optimization options. I posted a separate patch to update those.
