This is a bit different than what I expected to find as the initial use case
because it wasn't printing a range. With this change we go from printing only
the .start to printing the range. Seems the wording of the dev_ message could
change too since 'dpa' has been replaced with a 'dpa range'.
There are a few places that print the range now and can be cleaned up w this
specifier. Those are the real 'uglies' like this:

I guess you could (ducks) pick them all up here, or we can leave it
for a future cleanup, or we can just say no cleanups and we'll use
%pra going forward only.
