Thanks for the review, but I don't agree with that proposed change. To
me, it seems too much like insisting that a function must document the
things it doesn't do. Granted, saying "this function doesn't overwrite
*endp" is a much more reasonable thing to document than "this function
doesn't try to compute pi to 3,141,593 decimal places," because the
latter is less likely to be something that the user would expect it to
do. But I feel like the comment is clear enough as it is, so I've
committed the patch without change. If more votes in favor of
adjusting the comment emerge, we can certainly reconsider.
