Tests failing in roxygen2

[jennybc]

I first saw this locally then checked that same is happening on CRAN. Something about the most recent common mark release seems to have changed behaviour that is tested in roxygen2.

A bit more info from a test case. commonmark::markdown_xml("foo [func()] bar") is returning:

<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n
<!DOCTYPE document SYSTEM \"CommonMark.dtd\">\n
<document
	xmlns=\"http://commonmark.org/xml/1.0\">\n  
	<paragraph>\n    
		<text xml:space=\"preserve\">foo </text>\n    
		<link destination=\"R:func()\" title=\"\">\n      
			<text xml:space=\"preserve\">func()</text>\n    
		</link>\n    
		<text xml:space=\"preserve\"> bar</text>\n  
	</paragraph>\n
</document>\n

whereas the expectation (previous behaviour?) is:

<link destination=\"R:func\\(\\)\" title=\"\">\\s*
	<text>func\\(\\)</text>

Not sure who needs to adjust to whom here.
