grep: -P (--perl-regexp) \d: match only ASCII digits
Prior to grep-3.9, the PCRE matcher had always treated \d just
like [0-9]. grep-3.9's fix for \w and \b mistakenly relaxed \d
to also match multibyte digits.
* src/grep.c (P_MATCHER_INDEX): Define enum.
(pcre_pattern_expand_backslash_d): New function.
(main): Call it for -P.
* NEWS (Bug fixes): Mention it.
* doc/grep.texi: Document it: with -P, \d matches only ASCII digits.
Provide a PCRE documentation URL and an example of how
to use (?s) with -z.
* tests/pcre-ascii-digits: New test.
* tests/Makefile.am (TESTS): Add that file name.
