Hi,

the documentation for `git update-ref` has this sentence:

It also allows a "ref" file to be a symbolic pointer to another
ref file by starting with the four-byte header sequence of
"ref:".

After fumbling around a bit and getting errors like 

fatal: ref:refs/remotes/origin/test: not a valid SHA1

I looked in builtin/update-ref.c and I do not see a call to refs_update_symref
nor any checks for "ref:". Am I missing something here?

Thanks,
Bence
