delint



I recent post on one of the sage lists complained about their
implementation of dirac_delta integrals.  I was curious and
tested maxima's support.

Grep(1)ing, I found delta.mac and tried:

 load(delta)&
 delint(delta(x),x,-1,1);

which returned 3.  In fact, it returned three for every set of limits
I tried, whether minf,inf or 0,0 or anything else.

The post I reacted to suggested the answer for -1,1 should be 1.

Do I misunderstand how delta.mac is supposed to work?

I run 5.24.0, currently on sbcl.
