Before this patch, on FreeBSD 6:

  $ printf 'x y z\nx \xa0 y z\n' > in
  $ LC_ALL=fr_FR.UTF-8 uniq -f2 in|tr ' ' .
  x.y.z
  x. .y.z

With the patch:

  $ LC_ALL=fr_FR.UTF-8 uniq -f2 in|tr ' ' .
  x.y.z

This also affected many other locales:
for i in $(locale -a); do test $(LC_ALL=$i ./uniq -f1 in|wc -l)
  = $(LC_ALL=$i uniq -f1 in|wc -l) || echo $i ; done

help2man: fix perl 5.10 problem properly

* man/help2man: Do pull LC_ALL via "use POSIX".
Instead, limit the importing of gettext-related symbols
to just those two we'll use: gettext and textdomain.

help2man: avoid failure with Debian unstable's Perl 5.10.0

Avoid failure that produced this diagnostic:
Constant subroutine main::LC_ALL redefined at /.../Exporter.pm
* man/help2man: Don't include LC_ALL in the "use POSIX" list,
since Locale::gettext->import will get it.

base64 module: adjust API so it's compatible with gnulib's

* gl/lib/base64.c (base64_decode_ctx): If no context structure was passed in,

* gl/lib/base64.h (base64_decode): Macro for four-argument calls.
(base64_decode_alloc): Likewise.
* src/base64.c (do_decode): Call base64_decode_ctx instead of base64_decode.

tac: avoid segfault for e.g., "echo > x; tac -r x x"

* src/tac.c (tac_seekable): Move local "regs" declaration out
to file scope, so its values aren't clobbered between calls.
Discovered by Cristian Cadar, Daniel Dunbar and Dawson Engler,
reported in http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/13501

* tests/misc/chcon: Skip this test if mcstransd seems to be running.

tests: avoid spurious "make check-root" failure

* README (Running tests as root): Also set PATH in suggested "sudo"
command.  This avoids failure of at least tests/cp/cp-a-selinux
when the default PATH does not contain /sbin.
* tests/cp/cp-a-selinux: Don't redirect stderr to /dev/null.
"mkfs" was failing due to /sbin not being in PATH.

Add Daniel Dunbar's lcov instructions to HACKING

* HACKING: New section `Finding things to do', points to TODO file and
gives instructions on generating an html coverage report as provided by
Daniel Dunbar.
* TODO: Add item for improving test coverage.  Point back to HACKING.
