I'm not sure it's a bug.  My guess is that it was by design
(for whatever reason).  Perhaps Eli or someone else can
enlighten us.

I kinda doubt it was an oversight.  All of those bindings
are together, and the person who changed the Meta bindings
likely searched for `forward-word', not "[M-right]" or
"(kbd "M-<right>")"...

In `bindings.el':

 (global-set-key [M-right]  'right-word)
 (define-key esc-map [right] 'forward-word)
 (global-set-key [M-left]   'left-word)
 (define-key esc-map [left] 'backward-word)
