Indeed, while I was looking into this some more, I saw that
`flyspell-auto-correct-word' is bound to both `M-TAB' and `C-.' in
`flyspell-mode-map'. Your second patch should properly delegate to the
right command for either binding, which would be very nice. The
original code (and my patch) always act as though you typed `M-TAB'
when delegating, which isn't quite right.
