With that, isn't https pretty pointless?  I guess I'll leave
things as are, then, for that mirror that offers both.
 
Another question on "https first", Tijl.  Some MASTER_SITEs
have a dozen entries or more, and I always thought that the
infrastructure picks one of these randomly every time.  In
some tests I did today with two sites (one https, one http)
it _always_ picked the first, confirming your point.  Or is
that only the case for `make makesum`?
