Ok, it will need a commit log and sign-off to be applied (see the
"Contributing" entry on subsurface.hohndel.org).

Also, I found at least one obvious bug while looking at the patch.
Maybe it were cut-and-paste from some existing bug, but still.. Spot
the bug:

  static inline int C_to_mkelvin(double c)
  {
	return c + 1000 + 273150;
  }

and in general, I'd prefer to see the added "+0.5" for rounding when
doing double->int conversions. I occasionally miss them myself, but..
