Nothing special was done in Debian side about this, so I guess this is
related to Emacs 23 itself. Are you using ispell.el as shipped with Emacs 23?

I tested with the same hunspell and roughly similar ispell.el (pristine for
emacs-snapshot and with the same backport changes for Emacs 23 and 24),
finding the problem only in Emacs 23.

I also tested with pristine Emacs 23 and I can also reproduce the problem,
so I guess the problem is in the emacs side. 

Since Emacs 23 is an old version, unless somebody points to the Emacs commit
addressing this, I do not expect this to be addressed.
