Correct.

Probably this is needed.

I do not think this has much merit. The usual tag-following rules AFAIK
assumes that if you have the commit C then you ought to have all the
ancestors of C, which does not apply at all for the shallow hack to begin
with, and if you make the rule apply for the shallow hack, you would end
up slurping the objects that are needed only for ancient versions, which
would defeat the objective of this patch, no?

It also is my understanding that the shallow hack is almost always used
with a depth of one, not a range, like "git archive | tar xf -", so if
anything, I would say a single-branch cloning has much higher priority
than following tags.

Will queue on 'pu'. Thanks.
