 change the 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.

 "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.

 (and more visible, probably) from a user point of view, if that
 "legend_label" parameter would be integrated in d.legend.vect, instead of
 having to set the label in d.vect to then have it displayed with
 d.legend.vect

 > I prefer to have it in d.vect as that is where the layer is defined. In
 d.legend.vect, this would be awkward as a d.legend.vect call could concern
 anything from 1-X layers and so potentially you would need X text fields
 to define labels and X is not defined beforehand. So, I would plead to
 keep it as is, but just to improve the handling of special characters,
 including spaces, in the text.

 ok, I see... Shall we then open a different enhancement ticket for "better
 handling of special characters and spaces in legend_label parameter of
 d.vect" and keep this one for the possibility of choosing which vector
 labels to show / not show in the vector legend??
