.. actually, I think I take that back.

We should make sure the use is the same (ie OC vs diluent, for
example), but even manually added pressure data we might need to
merge.

Why? We also do equipment merges not just across dive computers, but
when you merge two consecutive dives into one dive with a surface
interval.

So then we'd need to have some other logic fir that case.

I think I'll ignore it for now.
