The script extracts the comments and prototypes from module.c and does
some pre-processing, e.g. converts URLs to markdown links. The URL
regexp didn't account for '#', '?' (and a few more chars) so an URL like
`https://example.com/#section` was converted to markdown as
[https://example.com/](https://example.com/)#section
With this change, it's instead correctly converted to
[https://example.com/#section](https://example.com/#section)
Additional change: Removes an unused metadata field.
