+\r
+I have a separate branch (also sitting on top of the features branch)\r
+that implements "ghost" messages. The main intent is to fix a bug we\r
+currently have in threading, but it puts us in a good position to\r
+maintain state for messages we don't have the content of, including\r
+last modification times for deleted messages and pre-seeded tags for\r
+undelivered messages (useful for pre-tagging sent messages as sent,\r
+nmbug, notmuch insert, etc.)\r
