##  Tally/update the newgroup/rmgroup control log.
##  Merge in a log that contains newgroup/rmgroup control messages so that
##  the "control.log" file is updated to contain the new counts of how
##  often each group has been newgroup'd or rmgroup'd.  This is run by
##  scanlogs, which prepares this from the control-message handlers if
##  control.ctl specifies logging.
