Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility runs the named

|
|
is a digit from 1 to 9, are replaced by the
|
|
.Li d Ns \'th
|
|
following unused
|
|
.Ar argument .
|
|
In this case, the largest digit number of arguments are discarded for

.Ar command .
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width indent

Normally arguments are taken singly; the optional number
|
|
.Fl #
|
|
specifies the number of arguments to be passed to

.Ar command .
|
|
If the number is zero,
|
|
.Ar command
|
|
is run, without arguments, once for each
|
|
.Ar argument .
|
|
.Pp
|
|
If any sequences of
|
|
.Dq Li \&%d
|
