The idea is that people in general write their model files more or less
while interactively using WinBUGS / OpenBUGS and later on start
automizing with R2WinBUGS or BRugs. Then the file already exists.
Of course, we can add dome fancy stuff that applies write.model if an
expression is given in the argument "model".
I'll put it on the ToDo list.
