man.indent.lists — Adjust indentation of lists?
If the value of man.indent.lists is
non-zero, the width of the left margin for list items in
itemizedlist,
orderedlist,
variablelist output (and output of some other
lists) is set to the value of the
man.indent.width parameter
(4n by default). If instead the value of
man.indent.lists is zero, the built-in roff
default width (7.2n) is used.
