commit 850977345d02c1f331507a3152c4d121044e3418

    Don't let the Gnus summary format group create registry entries
    
    * packages/gnorb/gnorb-gnus.el (gnorb-gnus-insert-format-letter-maybe):
      This function was unilaterally creating entries because of its use
      of `gnus-regsitry-get-id-key'. Because it does not respect ignored
      registry groups, we should use lower-level functions that don't
      create an entry where there wasn't one.
