* With -P, patterns like [\d] now work again. Fixing this
has caused grep to revert to the behavior of grep 3.8, in that
patterns like \w and  go back to using ASCII rather
than Unicode interpretations.
However, future versions of GNU grep and/or PCRE2 are
likely to fix this and change the behavior of \w and 
back to Unicode again, without breaking [\d] as 3.10 did.
