Write File trouble.

[RMS@MIT-OZ]

Does anyone remember what the trouble was
that was fixed by making EMACS write a temporary file and rename it
on Twenex?  I know that it was changed because it lost in some
circumstances, but I forgot years ago what they were.

In any case, the reason why the changed Write File did not get seen
is probably that a variable MM Write File exists, and it overrides
any definitions from libraries.  In order to change the function
Write File that is used, you must set that variable to the new definition.
