The reason is that gnubg has code to check if stdout is a terminal - 
            fShowProgress = isatty( STDOUT_FILENO );

This is meant to prevent diverted output from being filled with
intermediate results, for example, rolling out that one position
produces something like 300K of output. Under Unix, programs such as 
script allow you to capture the full output:

$ script gnubg.out
script started, output file is gnubg.out
$ gnubg -t ...
$ exit
script done, output file is gnubg.out

captures everything. The bad news is that in the non-gui version, I
can't find any command you can run to see the rollout results when
they are completed. 

What's needed is a command which shows the rollout results, which is
not as easy as it sounds, as the current output is done as a callback
function from within the rollout code.
