The feature is a hack, which is why it's off by default. Mintty simply
sends the number of arrow left/right keypresses that it thinks should
take the cursor to the right position, whereby ^[[C is the keycode for
arrow right. Obviously this relies on the application handling such
keypresses in the expected way.

However, are you finding that the arrow keys work where the mouse
feature doesn't? I think there is a problem with mintty here actually,
in that it doesn't take account of application cursor key mode when
sending those mouse events. (In that mode, the arrow left/right
keycodes change to ^[OD and ^[OC.)
