bug#9347: PR(1) -t/-T negates :STOP_PAGE

[beaker]

The issue:
Running pr(1) with eith the -t or -T options appears to negate the --page
option's :LAST_PAGE optional argument.  The documentation does not mention
this effect; either the documentation or the program should be updated to
address this.

Illustration of issue:

$ wc -l foo
144 foo
$ pr +1:1 foo | wc -l
66
$ pr +1:1 -t foo | wc -l
144
$ pr +1:1 -T foo | wc -l
144

Version and system info:

$ pr --version | head -n1
pr (GNU coreutils) 7.4
