Heh. I think we should probably call read_refs() just once to read them
all (when most of them are packed, that's cheap), and then after that,
have some way to just check for a match on the refs we have cached.
I had a look at the exclude_existing function in show-ref. That uses
for_each_ref to build a path_list, and path_list_has_path to do the
filtering...
Using that I get (worst of 5, warm cache):
