No, not at all.

Thanks, this seems to fix the problem.  I take it that you've verified
it doesn't re-introduce the original bug?

I only see this in a text-mode frame (in my case it's "<mouse-1>
<indent-pp-sexp>").  On GUI frame, there's no "translation".

I think you are right, as I see the same problem in Emacs 24.5.

In any case, this is a much more minor bug than the one I reported, so
please install your changes on the release branch.  Bonus points if
you can find where does the "translation" come from.

Thanks.
