Consider enabling autolink extension in markdown_xml

[jeroen]

The gfm autolink extension will automatically detects URLs and email addresses in markdown text and turn them into hyperlinks. See gfm-autolink spec for details.

roxygen2/R/markdown.R

Lines 213 to 216 in a34bdf7

	md_to_mdxml <- function(x, ...) {
	md <- commonmark::markdown_xml(x, hardbreaks = TRUE, extensions = "table", ...)
	xml2::read_xml(md)
	}

Additional benefit is that this prevents a URLs from getting spell-checked as if they were plain text.

Yeah, sounds like a good idea.

I tried turning this on and it broke a test because surprisingly it will autolink the url in this text:

#' [link % text](https://foo.bar/link%20target)

This is probably not coming from commonmark directly, but something we're for our hybrid Rd-md mode, but either way I don't think it's worth running down in more depth as the parser is already pretty fragile.

Fair enough, thanks for giving it a try.
