Minor clean-ups

• Clean up white space in output.

Format update

• Format types as code snippets
• Empty line before header (helps some Markdown parsers)

Word wrap, format tweaks

• Word wrap verbatim section
• Skip type and name from titles (for now)
• Prefix little title before list of parameters

First functional release

This works well enough for my immediate needs. Test suite and more versatility to come with 1.0.
