Old *Dired-n* buffers that have been successfully Q'd from should
either go away since re-entering them makes little sense in the
state they are left in, or better still they might flush all the
D'd lines and allow you to reuse them.
What is needed is a way to find out if a host supports undeletion.
On hosts that do, the data structure would be correct (i.e. removing D's
from lines would offer to undelete the file.)
The data structure may not be correct if other people are using
the directory or if you have done other saves inbetween.
Actually, the data structure Dired has may not be correct even on the
first run. The probability of its being wrong goes up with time, but is
not interestingly related to whether you have Q'd out of Dired or not...
I'm not sure whether that makes your point more significant or less
significant, however. Sigh.
