If this is intended to be an internal function, then it should
probably be named __fontpath_from_fontconfig__.

  if (! strcmp (font_suffix, prior_suffix))
    if (nargin > 0)
      [status, font_list] = system (sprintf ("fc-list : file | grep '.%s'", 
font_suffix));
    else
      [status, font_list] = system ("fc-list : file");
    endif

Don't you want to avoid depending on grep being available, for
Windows?

If you do use grep, then remember that . matches anything, so you
probably want '\\.' in the sprintf format string.
