* Noteworthy changes in release 3.10 (2023-03-22) [stable]
	** Bug fixes
	  With -P, \d now matches only ASCII digits, regardless of PCRE
	  options/modes. The changes in grep-3.9 to make \b and \w work
	  properly had the undesirable side effect of making \d also match
	  e.g., the Arabic digits: ٠١٢٣٤٥٦٧٨٩.  With grep-3.9, -P '\d+'
	  would match that ten-digit (20-byte) string. Now, to match such
	  a digit, you would use \p{Nd}. Similarly, \D is now mapped to [^0-9].
	  [bug introduced in grep 3.9]
