anchor.diff:  
   *Flow:*
   
  - * Export patches from patches branch using `git format-patch`
  + * Export patches from the `patches` branch using `git format-patch`
    * Add these patches to dist-git and edit `.spec` file to apply them
    * Create new commit with the change (or amend previous with `-a`/`--amend`)
    * If a "%global commit asdf1234" macro declaration is present, rewrite
  
positive.code: 
  Show pretty diff of `requirements.txt`.
  
  See link:rdopkg-adv-requirements.7.html[rdopkg-adv-requirements(7)] for
  complete example of `reqdiff` and other requirements management actions.
  
  Use this to see how requirements changed between versions.
  
negative.code: 
  `update-patches` also supports filtering out patches based on matching a
  regex provided by a magic #patches_ignore comment in the spec file. This is
  useful, for example, in case the `patches` branch contains changes that are
  related to the CI/code review infra, that are useful to keep around but don't
  need to end up in the RPM.
