 label displayed. Not always the name of the vector map is the best option,
 especially if one is displaying for example only one category of an
 attribute. For instance, I have presence/absence points and only want to
 display presence points. I'd like to be able to tweak the label to be
 "presence" instead of the name of the vector map.

 Yes, but this does not seem to like spaces. If I use a label such as
 "Areas < 10e6" it only displays "Areas". Same with "Large Areas", I only
 get "Large" in the display. It does not make any difference if I enclose
 the text in quotes, or not.

 should go on the map but doesn't need to have a label in the legend.  If
 one disables the display of the map, it disappears from the legend, that's
 fine. But it would be great to be able to choose which items should have
 label and which shouldn't (but still be displayed).

 implement it. Currently you can use d.legend.vect output parameter to
 export the legend definition, remove the particular line, and use it as
 input.

 I tried just using one whitespace as lable, but then I get an 'x' in the
 display.
