   .Ss Scaling Widths
   Many macros support scaled widths for their arguments, such as
   stipulating a two-inch list indentation with the following:
   .Bd -literal -offset indent
   \&.Bl -tag -width 2i
   .Ed
 .  .
   .Pp
   The syntax for scaled widths is
   .Sq Li [+-]?[0-9]*.[0-9]*[unit] ,
   where a decimal must be preceded or proceeded by at least one digit.
   Negative numbers, while accepted, are truncated to zero.  The following
   scaling units are accepted:
   .Pp
   .Bl -tag -width Ds -offset indent -compact
   .It c
   centimetre
   .It i

   .It P

   Negative scaling units are now truncated to zero instead of creating
   interesting conditions, such as with
   .Sq \&sp -1i .
   Furthermore, the
   .Sq f
   scaling unit, while accepted, is rendered as the default unit.
