pcre2: newline any => anycrlf

Hello,

Currently pcre2 is configured with "--enable-newline-is-any". With
the option, the library treats 0x85 as a newline char. But in UTF-8,
0x85 is used at least for some casual Kanji chars. So the pcre2
cannot handle text which includes such the chars properly.

Since --enable-newline-is-any conflicts with using UTF-8, I think we
should change it to --enable-newline-is-anycrlf to avoid the
conflict.

https://github.com/PCRE2Project/pcre2/blob/pcre2-10.37/src/pcre2_internal.h#L663
657 /* In ASCII/Unicode, linefeed is '\n' and we equate this to NL for
658 compatibility. NEL is the Unicode newline character; make sure it is
659 a positive value. */
660
661 #define CHAR_LF '\n'
662 #define CHAR_NL CHAR_LF
-> 663 #define CHAR_NEL ((unsigned char)'\x85')
664 #define CHAR_ESC '\033'
665 #define CHAR_DEL '\177'
666 #define CHAR_NBSP ((unsigned char)'\xa0')

\u8005 is "\xe0\x80\x85" in UTF-8, which includes "\x85".
https://glyphwiki.org/wiki/u8005

test code in php:

<?php
$test = "\u{8005} hogehoge";
if (preg_match("/^(.+)$/m", $test, $match)) {
print("result: " . str_ends_with($match[1], "hoge") .
" (should be 1)\n");
}
?>

ok?


Specify --enable-newline-is-anycrlf instead of --enable-newline-is-any
which doesn't work properly with UTF-8 text. The former option treats
0x85, which is used for some kanji in UTF-8, as a newline char.w
