Emacs -Q

Paste or enter the following text into the scratch buffer:

Hello World. Hello world how are you?

Move cursor to the beginning of a word, such as "world".

Hit M-DEL  (backward-kill-word).  Word is killed as it should be, and point remains on "world".
Then, C-_ (undo).

Now, point is not where it should be (on "world", as before the change), but in the next line.

The problem was introduced in 44dfa86 (Aug 6, 2015).

(This was seen is on the emacs-25 branch.)
