Ahh. It's because cylinders_equal and copy_cylinders avoids
checking/copying the gasblen values on purpose.

The intent is to make sure that you can change the *type* of the
cylinder on multiple dives, while leaving the gas blend untouched.

But it does mean that you can't change the gas blend at all with the
"edit dive" interface.

Ho humm. I think we need to separate out the "master dive edit" case
vs the "other dive edits". Easy enough to do, I guess.
