Why are you bothered here? I am sorry but this part of the review is
absolutely pointless. I have no words to emphasize how high the
nitpicking level is. Please refrain yourself.

They just refer to the way the data is dumped, so "data" is in the name,
that's true. The fact that they share the same namespace is fortunate
but not super relevant either. I am following the hints discussed in v2
regarding the naming, I am not too attached to these, but they felt
correct, so I use them.

Yes. And?

I would have probably chosen a common name space from day 1 if I was
creating these now, but they are already two enums named
"DUMP_PREFIX". I guess we all agree it would be stupid to prefix all
enums "DUMP_PREFIX" anyway? And because you disgusted me from attempting
brave tree-wide changes, I will not rename them.

If I learned something on these mailing lists, it is that what is
natural for me might not be for others. The alphabetical order is not
respected. You already pointed that in your first review, so I chose
another place which felt more relevant... to me.
e, k, m, s, u. This is the alphabetical order. export.h is not at the
correct place, I am very sorry.
