Thanks for the bug report. That's new to coreutils 9.1, and is a big 
enough fail that it suggests we'll need a 9.2 sooner rather than later. 
I introduced the bug when fixing an earlier bug (sorry).

I installed the attached Gnulib patch, which should fix the bug in 
Coreutils, with the attached two Coreutils patches to update to the 
latest Gnulib, and to add a test case for the bug.
