[Therion] Therion and DEM

[Marco Menchise]

Hi,I also tried to lower the DEM accuracy by cutting digits after the point
but I got same error:  line too long. In my case I have only 3 digits.

I would know if it is a Therion limit and if it is somewhat possible to
overcome it by, for example, recompiling Therion.
