Ahhhh, thanks. You're right that "clone" is "special" in that way
and requires unusual order---I forgot about that.

Sorry, but I didn't realize that this is just a work-in-progress
that shows an early "only local transport is covered" preview. I
think, modulo that the access(mkpath()) thing should be in the "if
(is_local)" block, the patch covers the case of local transport well
enough. I think by "four types of transport" you mean ssh://, git://
https:// etc., but they all go through the same transport API, so
hopefully once one of them, say, git://, is covered, that would take
us a long way.
Thanks.
