Comparing the above with the current git version I see that you are

Your suggestion would make the first or last interval significantly
different from the others.

Of course the probability that an observation happens to hit the border
is basically 0 (unless you are really having a discrete distribution and
should be using frequency tables instead of histograms.)

I don't think this maximum/minimum cutoff should really ever be equal to
the value of an observation.
