Looks good, except I was almost hoping for one modification:

In this format, "src" makes sense as a generic sha1_name, and _not_
necessarily limited to a ref-name.
IOW, there's really no reason to not allow
git-send-pack .. dest .. <sha1>:dst-ref
where "<sha1>" may be something else than a ref (but a ref obviously ends
up being one such thing).
For example, let's say that I've got stuff at the HEAD of my tree that I'm
not quite ready to push out yet, but I _do_ want to push out the parent of
the current head. I'd love to be able to just do
git-send-pack parent $(git-rev-parse HEAD^):master
and there's no real reason why that syntax shouldn't just work: it's
entirely logical to say "I want to push out the parent of my HEAD as
'master' on the other end", and that's _exactly_ what the above says.

I think "src" should just be seen as any random SHA1 name, and we should
use "get_sha()" to convert it to a SHA1.
In contrast, "dst" is obviously a real ref name, and as such:

That makes your next rule a bit iffy, though:

since "src" from a local standpoint isn't really a ref-name at all.
But hey, your current patch looks fine already. It doesn't _quite_ do what
I had in mind, but it gets very very close.
