Run this command to remove the factored-out "fail=0" lines.
perl -ni -e '/^fail=0$/ or print' $(g grep -l '^fail=0$')
* tests/test-lib.sh: Initialize fail=0 here, not in 300+ scripts.
* tests/...: nearly all bourne shell scripts
Suggested by Eric Blake.
* src/md5sum.c (main): Set stdout to line buffered mode
to ensure parallel running instances don't intersperse
their output. This adds 5% to the run time in the worst case
of many zero length files, or 2% with standard file sizes.
* src/sum.c (main): Likewise.
* tests/misc/md5sum-parallel: New test for atomic output.
* tests/Makefile.am: Reference it.
* NEWS: Mention the fix
