Hi Christoph,

i prefer first solution, but solution 2 is fine if you are sure not to
add new bugs.
Adding something like (not tested)
  case "$@" in
     *.gz | *.bz2 )
            echo "xdvi does not display compressed files, try with texdoc." 1>&2
            exit 1 ;;
  esac
in the script is sufficient to help users finding right command.
