Personally prefer the current way. It conserves rightward space
enough so that one can usually fit the whole path on one line. If we
switched to URLs, many more lines would wrap past 80 cols.

Doesn't the RA layer already answer this question, in the *NEW_REV
argument to ra_lib->get_commit_editor()?

  svn_error_t *(*get_commit_editor) (void *session_baton,
                                     const svn_delta_editor_t **editor,
                                     void **edit_baton,
                                     svn_revnum_t *new_rev,
                                     const char **committed_date,
                                     const char **committed_author,
                                     svn_stringbuf_t *log_msg);

So after the commit, libsvn_client knows the new revision, and could
call pass it to some libsvn_wc post-commit function...
