Ran again after apt-get upgrade took me to 8.3 and libc6
2.19-18+deb8u2. Results similar, de_DE.utf8 has inconsistencies but
nothing else. So Debian stable is affected. (Just noticed that
Stephen Frost's output from the same OS reports a broken lb_LU.utf8
too, but after conferring on IRC it seems that may be because I
installed "locales-all" (precompiled) which didn't give me lb_LU.utf8,
and he generated all locales which apparently does.)
