Thank you for the report.
I confirm that GNU pr (even the latest, from coreutils-8.12)
is not compatible with the pr from Solaris 10:

    solaris$ seq 9|/usr/bin/pr -t -f -l3|grep -c '^L'
    3
    solaris$ seq 9|pr -t -f -l3|grep -c '^L'
    0

The source of pr is the ugliest and least maintainable (by far) in coreutils,
but we have decent test coverage for it, so we should be able to fix this soon.
