Comment:
As Martin pointed out, some features are not going to ever pass. (Like 
running LANG=c ./bzr selftest will always be missing unicode).

But aside from that, I would be happy to see the pqm's 'make check' run 
as:

         python -Werror ./bzr selftest --strict -v $(tests)
         @echo "Running all tests with no locale."
         LC_CTYPE= LANG=C LC_ALL= ./bzr selftest -v $(tests)
         python -O -Werror ./bzr selftest --strict -v $(tests)
