I am of two minds.

Looking for "\(\.\|->\)ref_name" used to ignore refname fields of
other structures and let us focus on the ref_update structure.  Yes,
there is the ref_lock structure that shares ref_name to contaminate
such a grep output already, but this change makes the output even
more noisy, as you have to now look for "\(\.\|->\)refname" which
would give you more hits from other unrelated structures.

On the other hand, I do not like to name this to "update_refname" or
some nonsense like that, of course. A reference name field in a
"ref_update" structure shouldn't have to say that it is about
updating in its name; it should be known from the name of the
structure it appears in.

So I dunno.
