Thanks for looking into this.

I don't think this belongs on menu `Mark', however.

It belongs on menu `Operate', as it operates on the
(typically) multiple files that are marked (or flagged).

Menu `Mark' is for marking files, not for acting on
marked files.

IMO, it would not be good to start mixing up marking
with acting on marked files, on the same menu.  That
would set a bad precedent.  Once things get set in
an Emacs menu, it seems to take a major earthquake
to later change them, so it's better to try to keep
things clear from the outset.

[When I said in my previous post, that Dired+
has a `Delete' submenu, I should have mentioned
that it is on menu `Multiple' (which corresponds
to vanilla menu `Operate'), not on menu `Marks'
(which corresponds to vanilla menu `Mark'.]
