grep: -x now supersedes -w more consistently
* NEWS, doc/grep.texi (Matching Control): Mention this.
* src/dfasearch.c (EGexecute):
* src/pcresearch.c (Pcompile):
Don't get confused by -w if -x is also present.
* src/pcresearch.c (Pcompile): Remove misleading comment about
non-UTF-8 multibyte locales, as PCRE doesn't support them.
Calculate buffer sizes more carefully; the old method
allocated a buffer slightly too big, seemingly due to luck.
* tests/backref-word, tests/pcre: Add tests for this bug.
