halrun -f option broken in master

It was brought to my attention that starting halrun with the -f option
but no file name is broken in master.
This will break pncconf and stepconf live testing and any other
program that does something like this: (in python)
 self.halrun = os.popen("halrun -sf > /dev/null", "w") 

the reason seems to be the upgrade Dewey added to halrun.in
 a snipit:

INTERACTIVE=""
inifile=""
theargs=""
while getopts "f:hi:kqsvIRQTUV" opt ; do
  case $opt in
    h) help; exit 0;;

    U) halcmd -R
       halcmd stop
       halcmd unload all
       $REALTIME stop
       exit 0;;

    f) filename=$OPTARG;;
    i) inifile=$OPTARG;;

by using getopts with f:  halrun now requires the -f option to always have
a file name.

Is there a way to fix this?
