    usr.bin/undo: Remove redundant history collection
    
    collect_history(fd, &error, &tse_tree);
    is done right before this unconditionally. If the previous
    collect were empty, this collect after if(cmd == CMD_DUMP)
    will most likely be empty.
    
    (It also doesn't really matter if the result has changed
    before and after if(cmd == CMD_DUMP) conditional since that's
    not what this program cares about anyway)
    
    Also see 3260eed4.
