Subject: [PATCH] Remove dead constants and unused `AnonClass` class
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- `RDoc::AnonClass` — documented as "never used", no references
- `RDoc::Generator::Darkfish::VERSION` — never referenced
- `RDoc::Markup::Formatter::InlineTag` — never instantiated after inline parser rewrite
- `RDoc::Markup::ToHtmlCrossref::CLASS_REGEXP_STR` — aliased but unused
- `RDoc::Markup::ToHtmlCrossref::METHOD_REGEXP_STR` — aliased but unused
