bug#18892: few test failure with 'grep-2.20.72-d512'

[Jim Meyering]

For the record, you may want to run something like this to survey
whether \w matches E-acute across all  installed zh_CN locales:

(here's output from an os x 10.9.5 system -- on debian unstable and
fedora rawhide, they're all "0"s)
$ for i in $(locale -a|grep -i cn); do printf '\303\251'|LC_ALL=$i
src/grep -q '\w'; echo $?: $i;done
0: zh_CN
1: zh_CN.eucCN
1: zh_CN.GB18030
1: zh_CN.GB2312
1: zh_CN.GBK
0: zh_CN.UTF-8
