docs: Remove the given items from the index and optionally from
          the working tree as well.
  
          :param items:
              Multiple types of items are supported which may be be freely mixed.
  
              - path string
                  Remove the given path at all stages. If it is a directory, you must
                  specify the r=True keyword argument to remove all file entries
                  below it. If absolute paths are given, they will be converted
                  to a path relative to the git repository directory containing
                  the working tree
  
                  The path string may include globs, such as *.c.
  
              - Blob Object
                  Only the path portion is used in this case.
  
              - BaseIndexEntry or compatible type
                  The only relevant information here Yis the path. The stage is ignored.
  
          :param working_tree:
              If True, the entry will also be removed from the working tree, physically
              removing the respective file. This may fail if there are uncommitted changes
              in it.
  
          :param kwargs:
              Additional keyword arguments to be passed to git-rm, such
              as 'r' to allow recursive removal of
  
          :return:
              List(path_string, ...) list of repository relative paths that have
              been removed effectively.
              This is interesting to know in case you have provided a directory or
              globs. Paths are relative to the repository.
