[Message part 1 (text/plain, inline)]

Hello.

Recipe to reproduce this bug, starting from emacs -Q:
1) C-x b test
2) M-x text-mode
3) Type something like this:
One sentence.
Other sentence.

4) Go to the first sentence, after the period.  Type anything and then
type C-M-i to complete it.
I type "comple" and complete it to "complete".

5) I expect the cursor to be at the end of the word just completed.  But
I see it moving to the next line.  With different words completed, the
exact position changes, but to me the cursor always ends up in an
unexpected position.

Best regards,
Mauro.

Looks like it expects you to invoke the command at the beginning of a
word.

I see.  That works as I expected, right.

But what I described still looks like a bug to me, though...I mean,  I
think the user shouldn't have to type M-b to then type C-M-i, in order
to be able to continue typing after the completed word.

Furthermore, the documentation under Spelling, in the Emacs Manual says:

     Complete the word before point based on the spelling dictionary
     (‘ispell-complete-word’).

and then:

     Insert the beginning of a word, and then type ‘M-<TAB>’;

Note the "before point".  That's what I did.  The only thing different I
did was that I wanted to complete a word that was not at the end of the
buffer.  And knowing only that much, I expected the cursor to be at the
end of the completed word.

It's a bug, no doubt.

Yup.  Now fixed in Emacs 28.
