REVISION SUMMARY
  The unescaped hyphen caused a build failure with pcre2-10.30 due to a broken
  regex: 'syntax-highlighting/data/syntax/rest.xml" line 27 broken regex:
  "^\\s*\\.\\. [w-_\\.]+::(\\s|$)" problem: "range out of order in character
  class" at offset 12'.
  
  The pcre2pattern documentation says this:
  
  "Perl treats a hyphen as a literal if it appears before or after a POSIX class
  (see below) or before or after a character type escape such as as \d or \H.
  However, unless the hyphen is the last character in the class, Perl outputs a
  warning in its warning mode, as this is most likely a user error. As PCRE2 has
  no facility for warning, an error is given in these cases."

TEST PLAN
  cmake && make && make test works fine pcre2-10.30, quick look at
  http://docutils.sourceforge.net/FAQ.txt in kate seems fine.
