Comment:

 the idea of adding boundary style option to vareas sounds reasonable
 enough.

 I'm not very much in favor of overridding the vector legend's
 representation, better I think to first fix any core problems so that
 would never be thought of, instead of adding another work-around for a
 program defect.

 note that using "color none" is slightly different than "color white" in
 your example:
 {{{
 vareas lake
   color white
 }}}

 In the case of 'color none' the dashed lines appear on top instead of
 below the area fill, and you might consider 'width 0.5' with it.


 also fyi a while ago I added some named shortcuts to the vlines 'style'
 instruction as the 01 thing is a bit weird to get used to: `solid, dashed,
 dotted, dashdotted` words auto-replace into a predefined 01 pattern.


 example reformed for the NC sample dataset:
 {{{
 g.region n=248500 s=242000 w=643500 e=649500 res=10

 ps.map in=- out=test.ps << EOF
 vlines lakes
  type boundary
  color red
  #style 1111110000
  style dashed
  label Lakes
  lpos 1
  end

 vareas lakes
  color none
  width 0.5
  fcolor blue
  label Lakes
  lpos 1
  end

 vlegend
   end

 end
 EOF
 }}}
