Can anyone explain to me why TeX sets \pagegoal to the g present
at the end of the page breaking algorithm rather than the g for
the best break?  Here's an example:

%% goal height=1288.40509, max depth=4.0
% t=22.0 g=1288.40509 b=10000 p=100 c=100000#
% t=34.0 g=1288.40509 b=10000 p=0 c=100000#
    .
    .
    .
% t=1042.0 plus 17.0 minus 12.0 g=1063.1112 b=190 p=150 c=440#
% t=1054.0 plus 17.0 minus 12.0 g=1063.1112 b=15 p=0 c=115#
% t=1066.0 plus 17.0 minus 12.0 g=1063.1112 b=1 p=100 c=201
% split254 to -16.83324,12.0 p=-10000
% t=1078.0 plus 17.0 minus 12.0 g=1051.1112 b=* p=0 c=*

> 1051.1112pt.
\doublecolumnoutput ...f D\dlr \showthe \pagegoal 
                                                  \global \prevpagegoal =\pa...
<output> {\doublecolumnoutput 
                              }
l.35 
     
I would have expected \pagegoal to equal 1063.1112, and I can
think of no use for the value that is heeded.  This really messes
up an output routine I'm working on!
