I presume you are talking about patch 91.
The current code is executing the body of the for loop for both end
points, cur and shared_value_abs, Besides being unnecessary, it means
the loop exits for a value outside of the valid range. This makes it
impossible to use the guarded_up/down functions, which never leaves the
valid range.
It *is* possible to make the patch smaller, by 18 lines, by leaving the
if statements untouched, like this:

}
However, the resulting code looks rather artifical. Would you prefer a
patch base on the above?
