Sorry for that.  I missunderstood your request.  I asked him after you 
wrote in the bug report:
-----
 1. Begin a discussion on emacs-devel about the behavior of this command.
    Solicit the wisdom of other old-timers on that list. Present your case
    dispassionately, in terms of what we gain from such a change.

I am still new here and i don't know who are the old-timers.  The 
first comes to my mind of course is Richard.  I wish to ask S. Kremer,
that would be great, but i have never seen him in this list so i am afraid 
he could pass away (?).  If that is the case, someone could be hurt if i 
try to contact him.
About beging a discussion on emacs-devel about this.  Well, i guess we 
already have this one: people can give us input here.  If we open another
thread we will have 1 bug report + 2 emacs-dev thread basically talking 
the same.  Not too tidy.

Yes, we can talk about that.
Eli suggestion would be consistent with Dired if, for instance:
I) C-u * . el RET
;; unmark
II) C-u C-u * . el RET
;; prompt for the marker char.

IMO we should not put extra care in one hypothetical user X who
spend 22 years doing:
C-u 65 * . el RET
I mean, we should not invert the number of C-u's in I) II), because:

1) It's impossible such X user does exists (at least in this
   Universe); and in case sh?e does exist i wish i will never face
   this person at night in a lonely dark street; or i would have a drink
   with her to explain that we are in XXI century, and now the computers
   accept text when they prompt for a character.  Who knows, maybe after
   that she pay the drinks.
2) We private zillions of 'real' Dired users to naturally unmark files
   by extension as they like to do with other Dired marking commands.
