sed: fix \b DFA-bug in C locale
Under some conditions, \b would mistakenly fail to match. E.g.,
this would mistakenly print "123-x" instead of "123":
echo 123-x|LC_ALL=C sed 's/.\bx//'
* NEWS (Bug fixes): Mention it
* gnulib: Update to latest, for DFA regression fix.
* testsuite/word-delim.sh: New file, to test for the dfa.c regression.
* testsuite/local.mk (T): Add it.
