I think these should be two patches: one to make them all auto-refresh,
and another to make it conditional. That serves the purpose of (a)
bisecting a regression to one or the other, and (b) we can bikeshed on
the interface and appropriateness of the don't-refresh flag :)

I don't see that being anything other than an obvious win, unless there
is some obscure reason for it. But yeah, seems like a good thing to do.
