Should owl reading declare win if the original stones are captured?

[gunnar]

This ticket is a successor of #43.

The current policy of the owl reading is to declare win if all the original stones have been captured. This is problematic if reading is done for a light stone which it would be fine to sacrifice while making life with other stones. In other situations it can be uninteresting if other stones live, e.g. having a small tail connect out to an already living dragon. This is particularly true if the original stones are cutting stones or part of a semeai.

Is there a way to resolve this problem?

An additional issue is that while capturing all original stones gives a win, this only happens by chance. No effort is made to capture even a single remaining tactically unstable original string.
