align grep -Pw with grep -w
For the -w option, with -P, we used to look for the pattern surrounded by
word boundaries. That's different from what grep -w does and what the
documentation describes. Now align with grep -w and the documentation by
using PCRE look-behind and look-ahead operators to match the pattern if
it is not surrounded by word constituents.
* src/pcresearch.c (Pcompile): Use (?<!\w)(?:...)(?!\w) rather than
\b(?:...)\b.
* NEWS (Bug fixes): Mention it.
* tests/pcre-w: New file.
* tests/Makefile.am (TESTS): Add it.
This complements the fix for http://debbugs.gnu.org/16865
