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

[積丹尼 Dan Jacobson]

And now that I have become more sensitive to the bug, I notice it just
happened again:

OK now today I was really trying to use flyspell-auto-correct-word,
but my cursor happened to be just past the "t" below.

As there really isn't much spelling to be corrected at "t", I started
noticing in the minibuffer (*Message* buffer):

Auto-saving...done
Corrections: unkind unkinder antonym inking envenom uncanny unkonwm unknown 
unkind
Corrections: unkinder antonym inking envenom uncanny unkonwm unknown unkind 
unkinder
Corrections: antonym inking envenom uncanny unkonwm unknown unkind unkinder 
antonym
Auto-saving...

OK as I didn't notice anything change (that's why I hit
flyspell-auto-correct-word the second etc. times, to see what it was up
to, where.)

So obviously those "Corrections: unkind unkinder..." mean that it was
indeed changing something off the screen and I will have to proofread
the entire draft to hopefully find where.
You might say "just use undo", but one fears that might even mess things
up further, so we chicken out.

P.S., one would think "just run a spell checker on your article."
Well that only detects misspelled words and where ever that word was,
alas, it is no longer misspelled now.

Wait (via searching for the last word in the last *Message* I found it,

That's right, way at the top of the message (way off the top of the
screen)  I was composing, it changed some word into "antonym".

Thank goodness I can run "undo" on just a region, revealing the original,
