Examining further, I just don't know how to do this in shell. Basically, 
what I want is the list of parents of all bases, but those bases might 
not be explicitly mentioned, e.g., master --since=10.days.ago and I 
don't understand any direct plumbing call that will give me the list of 
parents in the general case. At the expense of extreme slowness I can do 
some of this invoking sort and uniq with long lists of objects. The pain 
in doing that on the sender side is definitely worth the potential gain 
on the receiver side (I now remember I tried that a while back, was able 
to do something reasonable in Python using sets, it died in bash).
