Not only are these lines long in our source, they are long in the
generated libnbd.h.  I would not be opposed to a followup patch that
tries harder at keeping the generated file under 80 columns (but there
are already places where that is harder than this snippet - such as
the generated declaration of nbd_aio_opt_list_meta_context), but it
does not need to happen in this patch.

And while I mentioned in 01/29 about the possibility of a C code
formatter as a CI step for *.[ch], it would be even harder to insist
that generated code matches a given style (it's always a nice goal for
generated files to be human-readable where possible, but I'd much
rather sacrifice that if it gets in the way of actually implementing
the generator concisely).
