  Yes.  The user can apparently specify the font for legend text by using the
  "textfont" parameter.  Usage is:

	textfont font

  within the "legend" instruction set, where "font" is any valid font
  name as listed in the "Valid font names" section in the "p.map.new"
  manual entry.

  There are more than one problems here:
  * The manual entry is incomplete - it needs to specify all valid
    parameters.
  * The "textfont" parameter is valid in "legend", while it is invalid in
    the "text" instruction (just "font" is valid there).  Consistency is
    needed - users should not be guessing about valid names.
  * Sometimes it is difficult to decide what the best name should be -
    "textfont" is redundant, but it corresponds well with "testsize",
    "textsize", and "textcolor".  [I prefer the simple "font".]
  * All instructions that include text in p.map.new (e.g., barscale, grid,
    legend, text, etc.), should probably have a "font" parameter.

  BTW, my hardcopy 4.1 manual has the parameter "textfont" in the
  "text" instruction for "p.map.new", but my on-line manual has
  "font", which is the one that works in my current version of GRASS.
  If one doesn't work at your site, maybe try the other...

  [Remember:  p.map.new is alpha code.]
