Fixes #92 and is the only remaining code change I have (as opposed to wrapping Markdownify)

Hi! This breaks some working code, as there will be a few places with loads of empty lines, for example:

md('<blockquote><p>Hello</p><p>Hello again</p></blockquote>')


       > Hello
       > 
       > 
       > 
       > Hello again

Postprocess. It’s trivial, and easier to fix there than in Markdownify.
