I've run in to this as well.  However, depending on the context, the
punctuation might be . , ; ! : or whatever.  I don't see how LaTeX could
guess this from the context.

Easier would be to define yourself (or in the appropriate journal class;
perhaps that discussion will rear its ugly head again soon) things like
\period, \comma and so on which you could stick in before the
\end{equation}.  You could define them to correspond to their names or
just to do nothing as the style required.
