A few changes: * 0-arity type specs like the following previously would not have the expected 'variable.parameter' highlighting for the return type: -spec foo() -> Value when Value :: term(). * Highlight module, type and function docs as documentation comments and inject markdown into them. * Replace `#match?` predicates with `#any-of?` where possible. * Remove custom auto-pairs. Now that Erlang uses markdown for documentation, the asciidoc-style backtick-singlequote pair is no longer useful.
