OK, I'll fix this in the next commit.

BTW, please note a nice feature that when `windmove-create-window'
is non-nil, then the Meta-modifier is not necessary, i.e.
these key sequences should provide the equivalent result:

M-S-right M-.
  S-right M-.

because S-right will create a new window in that direction
before M-. is invoked in that manually created window
(when S-right is bound to windmove-right, and M-S-right
to windmove-display-right).
