Actually, consider the POSIX spec for pr.
Its description of the -t option says this:
-t Write neither the five-line identifying header nor the five-line
trailer usually supplied for each page. Quit writing after the
last line of each file without spacing to the end of the page.
Which I interpret as meaning pr should write neither those spaces
(the default trailer) nor the replacement formfeed that you get with -f.
So, unless we get an interpretation from the POSIX folks
that says otherwise, I'll leave GNU pr the way it is.
I've marked this issue as "done" for now, but you're welcome to reopen it.
