 Horizontal and vertical spacing and resolution
 ==============================================
 
 WoMan currently assumes 10 characters per inch horizontally, hence a
 horizontal resolution of 24 basic units, and 5 lines per inch
 vertically, hence a vertical resolution of 48 basic units.  (‘nroff’
 uses 240 per inch.)
 
 Vertical spacing and blank lines
 ================================
 
 The number of consecutive blank lines in the formatted buffer should be
 either 0 or 1.  A blank line should leave a space like .sp 1.  Current
 policy is to output vertical space only immediately before text is
 output.
