[TxMt] Disable softwrap in tm_properties?

[Carpii UK]

I often use TM as a general purpose text editor (and softwrap is useful in
those cases)
But for coding I never want it enabled.

Is there a way to set this is tm_properties, in a way that will override
the restored GUI prefs?

Various git posts and the FAQ suggest you can *enable* it in tm_properties,
even when gui setting has it disabled

But I'm not having much luck doing the inverse
