set different [on|off|nostack]

Set to make sure C<next> or C<step> moves to a new position.

Each line often may contain many possible stopping points. In a
debugger it is sometimes desirable to continue but stop only when the
position next changes.

Setting C<different> to on will cause each C<step> or C<next> command to
stop at a different position.

Note though that the notion of different does take into account stack
nesting. 

See also C<step>, C<next> which have suffixes C<+> and C<-> which
override this setting.
