    You are right :)

    'mgt' has this problem, and if my memory serves me well,
PilotGOne (for Palm) (at least it uses [tt] for writing). Moreover,
'sgfc' has an option to rewrite all pass moves to [tt] :? So I
thought that, although the '[]' form is the modern one, applications
should use the old one when possible, given that larger-than-19
boards are very rare in Go.

    I'm using 3.3.14, I'll upgrade to 3.5.1 right now. Thanks for
your help :)
