* src/frontend/postcoms.c :
bug fix, avoid $curplot (plot_names) being assembled from negative numbers
The variable `plot_num' is exclusively used to build plotnames,
via sprintf(plot_name, "dc%d", plot_num) expressions
Thus plot_num may never be decremented.
Otherwise expressions of sort
dc-2.var
can't be parsed
