Some corporate emails attach a long disclaimer to the body of every outgoing email message. It would be good to have some kind of indicator of end of message, so that the long disclaimer does not get included in the task notes.
e.g.
Do Something @context #today *folder
Some notes
Some notes
Some notes end.
This message is confidential blah blah blah blah corporate disclaimer...
Something simple like "end." "<eom>" will do nicely.
