get-max-undo-history

Returns the maximum number of undoables that will be remembered by the buffer. Note that undoables are counted by insertion, deletion, etc. events, not by the number of times that undo can be called; a single undo call often reverses multiple events at a time (such as when the user types a stream of characters at once).
