 In the grass7 wxGUI histogram tool, when "Histogram single raster" is
 selected, one can select only one raster at a time with the map selector,
 any new selection erasing the old one. However, one can type by hand
 raster1,raster2,etc and get the histograms for all these raster maps.
 Similarly, by selecting several maps in the Layer Manager and then
 launching the histogram tool, all selected maps are in the list.

 It would be nice if the map selector in the dialog would also allow
 multiple selections.
