tweaks: remove two superfluous assignments

Browse Source 
The variable 'last_action' is set at the end of these functions,
serving to prevent a fresh action from being merged with an older
action further down on the stack.  Setting 'last_action' before
exiting from undo()/redo() makes no sense.

Also adjust a sideways related old Changelog item.

* text.c: Reset openfile-> to OTHER after an undo or redo so we don't
mistakenly think this is an update when it's really an add. Also
fix an extra ; after an if statement which makes nano try to free
a struct which may be NULL.
