Almost, see below.

This is using the wrong tone for describing the issue: it regards
completion hints in Text Mode as a nuisance in most cases.  If it were
such a nuisance, we ought to make it off by default.

Instead, the text should describe the completion hints feature from
the POV of its being useful, and then say that the variable
text-mode-ispell-word-completion controls it.

Also, @vindex generates no text in the formatted manual, so you need
to mention the variable in the text as well, otherwise "this variable"
will allude to something the text doesn't mention.

Finally, please leave two spaces between sentences, per our
conventions.

This part is okay (modulo the 2 spaces between sentences issue).

Thanks.
