Yes, and that's what I complained about. However, your example doesn't
demonstrate my problem, since its deltas *are* real deltas, and
+1 + +0 == +1.

I guess a better example would be

old:
  open #1 #2
  closed #3
new:
  open #1
  closed #2 #3 #4 #5

which results in +2 for open (since #4 and #5 were opened) and +3 for closed
(since #2, #4 and #5 were closed), however the total issue delta is +2.  This
is why I think these numbers should be labeled "openings" and "closings".

two, excepting that thou then proceed to four. Tabs are right out.
