Twenex DIRED file display

[David Vinayak Wallace <GUMBY@MIT-OZ>]

When you are deleting the greatest version of a file with DIRED, the
confirmation display ought to indicate it with a ">" in the display.
Likewise, un-backed-up files ought to have a "!".

Also, it would be nice to be able to delete files had been GFRed.
Currently you get "File is offline" or somesuch.

If this had worked like it does under ITS, I wouldn't be running
DUMPER at this moment.
