Yes, something like that was supposed to be there - I'll need to check again why it isn't.

Yes - it will be eventually (the code for that is already just a little higher up in profile.c where it does so for decostops that the divecomputer reported.
But since I don't really trust the calculations, yet, I didn't bother… and frankly, for my dives I am always a million miles away from the calculated ceiling. 
Jan's dives violate it all the time, but he dives a rebreather and I'm not doing the calculations for those correctly, yet.   

Thanks for the patch - would you resend it with a commit message and Signed-off-by line so I can add it?
