Merge source and substitution configuration in reference docs

Asciidoctor User Manual: Applying Substitutions

---

I changed the code with sed script:

find . -name "*.adoc" -type f -print0 | xargs -0 gsed -i -f source.sed

source.sed:

:begin
/indent=0\]/,/\[subs="verbatim,quotes/ {
    /subs="verbatim,quotes/! {
        $! {
            N;
              b begin
        }
    }
    s/indent=0\]\n\[subs="verbatim,quotes/indent=0,subs="verbatim,quotes/;
}

Do the proposed changes fix any formatting issues in the generated documentation (HTML or PDF)? If so, which ones?

Or is the goal of this PR simply to merge the source and subs configuration lines?

Sorry. I didn't compare them, I just improved them according to AsciiDoctor's syntax.
