Subject: Escape hyphen in rest.xml regular expressions

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.
