Teach "git fetch" to accept an exact SHA-1 object name the user may
obtain out of band on the LHS of a pathspec, and send it on a "want"
message when the server side advertises the allow-tip-sha1-in-want
capability.

Hmm. The UI on this is a little less nice than I would have hoped.

Naming with unadvertised *refname*, not object name, needs protocol
extension for the serving side to expand the name to object name;
otherwise the receiving end wouldn't know what tip what it asked
resulted in.

And that belongs to a separate "expand refs" extension (aka
"delaying ref advertisement") that is outside the scope of this
series but can be built on top, as I said in the cover letter.
