This thread contains the bug-introducing patch in message https://lists.gnu.org/archive/html/bug-coreutils/2007-03/msg00160.html This is commit 553d347d3e08e00ee4f9df520b37c964c3f26e28. That commit removed the 'assume -e' part of the POSIX description of the -COLUMN option from GNU pr. Reverting this patch (i.e., adding the one deleted line back to pr.c) fixes *this* bug, but then re-introduces the bug reported in 2007, i.e., sub-test 'merge-w-tabs' of test 'pr-tests.pl' fails. Thanks, Erik -- If it ain't broke, don't fix it.
