* Reimplement `invertLiterate` without any dependency, tracking indentation levels (including inside lists); update literate test files to also check that no tests are skipped
* Drop Literate CoffeeScript’s support for executable code blocks inside list items (and also for second paragraphs or blockquotes in list items)
* Update Literate CoffeeScript docs to reflect current supported syntax
* Add tabbed literate test; modernize Markdown title heading
* Better parsing of Literate CoffeeScript files, including now correct parsing of tabbed .litcoffee files; and more accurate stack traces (assuming you don’t do your own word wrapping within list items)
* Swap Marked for MarkdownIt for parsing the Markdown of Literate CoffeeScript files; use MarkdownIt’s `map` property to preserve correct line numbers
* Literate CoffeeScript tests: remove trailing whitespace, fix spelling
* Literate CoffeeScript tests: add block quote test
* Literate CoffeeScript (tabbed, at least) seems to need a consistent starting indentation
* Restore test
* Reference links work now in MarkdownIt
* Breaking change in Literate CoffeeScript: code blocks within HTML tags must be unindented
* Breaking change in Literate CoffeeScript: code blocks within lists need a blank line separating them from the list item text
