clobbering match data on finishing the edit.

the date header works for intervals greater than a year, and when
incrementing or decrementing the month crosses one or more years,
adjust the year as needed.
(todo-read-category): If we're outside of todo-mode and there is a
current todo file, use it; otherwise, use the default todo file.
