[PATCH 2/3] show_ref(): remove unused "flag" and "cb_data" arguments

[mhagger@alum.mit.edu]

From: Michael Haggerty <mhagger@alum.mit.edu>

The function is not used as a callback, so it doesn't need these
arguments.  Also change its return type to void.

I suppose, though I didn't verify, that the old function signature was
a vestige of its earlier having been used as a callback function.  But
it doesn't really matter; the point is that the extra arguments are
currently not needed.
