father on:
\*n \" recalls string of name n
\v'-1m' \" vertical move up one (1) line (m), this is a value.
Note that \v for instance will interpret values by a default unit, used
in absence of one given. Thereas "Troff internally stores ... dimensions
in units that correspond to the particular device ..." (Troff Users
Manual, 1992, Ossanna/Kernighan). So in using number registers, i always
append 'u' (means basic unit). Otherwise things will be correctly
shifted out of sight, leaving you clueless that happend.
