When passing patterns to git-show-ref(1) we're checking whether any reference matches -- if none does, we indicate this condition via an unsuccessful exit code. We're using a global variable to count these matches, which is required because the counter is getting incremented in a callback function. But now that we have the `struct show_ref_data` in place, we can get rid of the global variable and put the counter in there instead.
