 When using spaces in the legend_label parameter of d.vect, d.legend.vect
 only displays the first word before the space.

 An example with the NC dataset:

 {{{
 d.vect map=hospitals at PERMANENT type=point,line,boundary,area,face width=1
 legend_label=Hôpitaux
 d.legend.vect
 }}}

 'Hôpitaux' is displayed correctly.


 {{{
 d.vect map=hospitals at PERMANENT type=point,line,boundary,area,face width=1
 legend_label="Les Hôpitaux"
 d.legend.vect
 }}}

 Only 'Les' is displayed in the legend.

 In the legend file, there is


 {{{
 Les Hôpitaux|basic/x|5|black|200:200:200|1|point|160
 }}}

 So the issue seems to be clearly with d.legend.vect.

 Another issue with white space:


 {{{
 d.vect map=hospitals at PERMANENT type=point,line,boundary,area,face width=1
 legend_label=" "
 d.legend.vect
 }}}

 Now I see an 'x' as the label in the map display. In addition, if I
 repeatedly click on 'Apply' in the d.legend.vect gui, the label displayed
 cycles through a series of weird combinations of characters, always
 beginning with the 'x'. Combinations I've seen include


 {{{
 xK[
 x[cc
 x[]
 x{
 }}}

 I would guess this some issue with memory address handling ?
