Sorry for the slow reply. For some reason I do not think your message
here made it to the list (but I don't see anything obviously wrong with
it).

Anyway, yes, I think it is worth dropping this hunk and re-sending the
else-if style fix as a separate patch (you may choose to re-send this
hunk as its own patch, too, if you want to argue for its inclusion, but
there is no sense in holding the actual style fix hostage).
