Fixed
- `:prog_name:` and other options can now contain multiple words (it used to stop at whitespace). (Pull 60)
- `::: mkdocs-click` directive is now recognized at the end of the file without needing an extra newline. (Pull 69)
- Code blocks are marked as text so that HighlightJS doesn't try to highlight the "syntax" as some random language. (Pull 61)
