X.P.OrgMode: Prune extra whitespace
X.P.OrgMode: Prune extra whitespace

This implements whitespace pruning at the end of a sheduled item or
deadline.  If we have a message like

    This is a message                +s today

it is expected that we created a heading of just "This is a message",
without the extra whitespace.
