Sorry, I don't understand.  My point was that typing C-M-i or C-. once
on a correctly spelled word doesn't try to change any other words in
the buffer.  Flyspell only does that if you invoke that command more
than once.

Are you saying that it happened to you when you invoked the command
only once?  That would be a bug, but then please describe a recipe for
reproducing it, because I don't see it here.

That would change its long-standing behavior in incompatible ways, so
I don't think we can do that.

I'm okay with making this behavior optional, but it will have to be on
by default, for backward compatibility.
