+The offending code is at line 1813 of lib/database.cc; the message is\r
+only indexed if the message-id is new.\r
+\r
+It might be sensible to move _notmuch_message_index_file into the other\r
+branch of the if, but even if that works fine, something more\r
+sophisticated is needed for the call to\r
+__notmuch_message_set_header_values; the invariant that each message has\r
+a single subject seems reasonable.\r
+\r
+Offhand I'm not sure of a good method of automatically deciding what is\r
+the same message (with e.g. headers and footer text added by a mailing\r
+list).\r
