DDP was warning when dumping refs to unopened or closed file handles

This just suppresses two warnings that don't otherwise indicate problems. In the future maybe check the "opened" flag? I'm not entirely sure one would distinguish between "closed" and "unopened" nor if one would want to.

Brilliant, thanks! Also, not only the open/closed status but also the seek position could be a good thing to show, maybe even a flag to let you see the surrounding area within the file. If not in DDP's core then at least as an external filter. What do you think?

Good ideas, all of them, although I'm not particularly motivated to look into them personally as I'm not in the habit of dumping file handles. I actually only encountered these warnings when I mangled a glob when writing the FORMAT test.
