Typographic transforms (---, quote pairs, ~) no longer touch verbatim text: @c/@code/@source_listing content and ^'...'^ spans show exactly the characters written. "^" before any punctuation character quotes it in every target (the apostrophe excepted: ^' opens a literal span), with the new :resolve option on @@@target declaring per-target renderings. The ^UUUU^ code-point form accepts 4-6 hex digits, the full Unicode range. The html output and transform spellings are polyglot (XML-valid), in preparation for an EPUB target. New suites: transform_test, character_test (engine), typography_test (SKS). (from dev 07ce5ea86a0a)
