I think the way to fix this problem is to modify the internal plotting
routines to count the lines in each subplot area.  Then we can know to
avoid issuing a replot command before any lines have been drawn in a
subplot area.  There should probably also be one of these count
variables for each plot window.  Currently, we only keep an overall
line count for all plots in all windows.
