I brought this up when the change was made to do
what's done now.  Originally Emacs put nil nil
in place of the specific region limits.

I don't recall whether a bug was filed for that
change or it was discussed in emacs-devel before
the change was made.  In any case, the decision
was to go with the "enhancement" that we have
now: the specific region limits.

IOW, FWIW, I agree with you.  I find myself
hand-replacing the numeric limits with nil's
fairly often.

I don't recall the reasons given for the change
to use the explicit numbers - if any reasons
were given.
