I hate to be a nit, but why this format and not the one that is
produced by `git ls-remote` and the native protocol?  I know its
pretty arbitrary either way, but since we already have a history
of using "SHA1 ref\n" why not continue that tradition here?

In the VCS protocol, the SHA1 is generally not known when simply listing 
refs, so I didn't have a useless initial field in that protocol; I just 
inherited having the line start with the name for this protocol.

In any case, I want to be able to support symrefs, so an extension to the 
tradition is required, but putting @<dest> before the name instead of 
after is easy enough.
