* TS: the "tag spacing" configures the size the of the gap that is       
  required after a paragraph tag.  This amount is added to the width of  
  the diversion created by the `IP` and `TP` macros to format the tag.   
  If that amount is greater than the standard indentation, a break is    
  emitted and the remainder of the paragraph is formatted starting on a  
  new output line, indented by the `IN` increment.  Default: 2n.         
  Currently, a value of 1n is used for this purpose.  (In groff 1.23.0,  
  it's stored in the internal `an-tag-separation` register, but not      
  readily user-configurable.)


_mdoc_ doesn't need to support this because it has other mechanisms for
achieving this, like a `Bl` macro with about a thousand configuration options.
