[DRE-maint] Bug#964322: ronn 0.9.1 does not render code blocks properly

Sun Jul 5 17:45:56 BST 2020

Package: ronn
Version: 0.9.1-1

I had to downgrade ronn as the new version fails to render the code blocks.

Here attached you'll find:
* the file code_blocks.7.ronn (a file provided with ronn-ng)
* the nice troff output produced by nroff 0.8.0: code_blocks.7
* the wrong troff produced by nroff 0.9.1: code_blocks.7.wrong
(in the same way I cannot use the new version to update the man pages
 of my projects like
 https://github.com/rd235/libstropt/tree/master/man)

Let me know if you can reproduce the bug.

Thank you in advance for your efforts to fix the bug.
