bug#19727: 25.0.50; setting a todo item to done puts point at the end of the buffer

[Robert Pluim]

Hi,

when I set an item to done in a todo-mode buffer, point ends up at the
end of the buffer, which is somewhat surprising. Attached patch
remembers where point was, and restores it.

Regards

Robert
