"pr" doesn't handle adjacent lines containing only '\n'.
They aren't included in the pagelength accumulation, so pages
containing them end up longer. Also the "-n" option fails on these
lines.  Here are the context diffs for one possible fix for that.

As usual, I claim these changes aren't suitable for anything.
