With my Emacs 25.1.1 `M-@' select the part of the word from the cursor
to the end of the word.  Moving the cursor left extends the region,
whereas moving it right unselects when over the initially selected
section and extends beyond that.

So if I have

  able baker charlie

and do `M-@' while on 'k',

         ker

is selected.  If I move left to 'a', then

  able baker

is selected.  If instead I move right to the final 'e', then

             charlie

including the space in front of the 'c' is selected.

Is that supposed to happen?  What's the use-case for the moving-right
behaviour?
