Surely, but there is no point revisiting. I simply misremembered
what we did at around 1354c9b2 ("refs: remove unnecessary "extern"
keywords", 2016-03-31).
As long as we know which way we are standardizing, I personally do
not have strong preference either way. I appreciate shorter-to-type
(i.e. missing "extern") but I also appreciate the more familiar and
logical declaration in a header file that indicates something exists
somewhere (i.e. explicit "extern") ;-).
Thanks.
