Bug#64560: tetex-bin: xdvi wrapper script creates useless tempfiles

[Julian Gilbey <J.D.Gilbey@qmw.ac.uk>]

Package: tetex-bin
Version: 1.0.6-6

I don't know what's happening with the xdvi wrapper script, but in the
meantime, /usr/X11R6/bin/xdvi has the following:

filename=${1+"$@"}
compress=0
tempfile=`tempfile -p tetex -s .dvi`
case "${filename}X" in
  *.gzX)
    gzip -d -c $filename > $tempfile
    compress=1
    ;;
  *.bz2X)
    bzip2 -d -c $filename > $tempfile
    compress=1
    ;;
esac
if test $compress = 1; then
    trap "rm -f $tempfile" 0 1 2 15
    filename=$tempfile
fi

So the tempfile is created anyway, but only removed if anything's
written into it.  Either the trap command should come immediately
after the tempfile command, or the tempfile command should appear in
both of the cases, thus:

filename=${1+"$@"}
compress=0
case "${filename}X" in
  *.gzX)
    tempfile=`tempfile -p tetex -s .dvi`
    gzip -d -c $filename > $tempfile
    compress=1
    ;;
  *.bz2X)
    tempfile=`tempfile -p tetex -s .dvi`
    bzip2 -d -c $filename > $tempfile
    compress=1
    ;;
esac
...
