plotutils graph 2.4.1 command-line processing bug

[Gerald Pfeifer]

I believe I found a command-line processing bug in graph from the
plotutils 2.4.1 package.

Consider the following little input file, called xtab:

  0       0
  5       5
  10      10

The commands
  graph -T X --x-limits 0 10 --y-limits 0 10 xtab
  graph -T X --x-limits 1 10 --y-limits 0 10 xtab
  graph -T X --x-limits - 10 --y-limits 0 10 xtab
as well as
  graph      --x-limits - 10 --y-limits 0 10 xtab -T X
all work as expected and open a window with the plot in it.

The following, however,
  graph      --x-limits 0 10 --y-limits 0 10 xtab -T X
  graph      --x-limits 1 10 --y-limits 0 10 xtab -T X
only print "garbage" like "#PLOT 1\noej...CDFHersheySerif..." on stdout.

(I don't think it the order of options should make a difference here,
and especially it shouldn't make a difference whether one specifies "0",
"1", or "-" as the lower bound of the --x-limits option.)
