Proper AST translation for hover docs #426
Description
We literally just take the hover doc and jam it into Markdown.
However, it's usually written using Doxygen markup, not Markdown. So we need to synthesize a Doxygen AST -> convert that to Markdown.
Here's one example where that falls down. Newlines just continue the paragraph in Markdown. But Doxygen uses \param to mark parameter lists.
For the param-specific issue, we could potentially just hack it by adding some ad-hoc translation. E.g. if the start of the line has \param <blah>, then emit * <blah>.
