I have the bash function config-path in lantern.sh.  Because the function name
contains a dash (config-path is permitted as a function name in bash), I do not
see the function name being listed when looking at the speedbar frame.  But 
other filenames ( that do not use dash "-" ) do get listed in the speedbar frame.

config-path ()
  {
    trklink=$(readlink -f "$0")
    dcnpath="${trklink%/*/*}"
    frcpath="${dcnpath}/fractr"

    case $1 in
      decuneus)  echo $dcnpath ;;
      fractr)    echo $frcpath ;;
      *) ;;
    esac
  }
