bug#30462: flyspell-auto-correct-word 'corrects' more than the current word

[積丹尼 Dan Jacobson]

    C-M-i (translated from <escape> <tab>) runs the command
    flyspell-auto-correct-word (found in flyspell-mode-map), which is an
    interactive compiled Lisp function in ‘flyspell.el’.

    It is bound to C-., C-M-i.

    (flyspell-auto-correct-word)

    Correct the current word.
    This command proposes various successive corrections for the current word.

Well it turns out if the current word is already correct, then it
searches backward up to several sentences looking for another word that
it can correct.

Which can have disastrous consequences when the boss reads the final
draft of what you sent him.

Therefore it would be best if this command would limit its helpfulness
to what it says in the docstring: the current word.

Which to me means not some word 30 words back.
