pcre2grep related to Windows and Cygwin support.

+52. Change 3(g) for 10.23 was a bit too zealous. If a hyphen that follows a
+character class is the last character in the class, Perl does not give a
+warning. PCRE2 now also treats this as a literal.

+53. Related to 52, though PCRE2 was throwing an error for [[:digit:]-X] it was
+not doing so for [\d-X] (and similar escapes), as is documented.
