arg.h: remove unused ARGNUM* macros

This was always broken.

Reproduce:
	focus client on second monitor, spawn dmenu with -m 0.

Result:
	Old wrong behaviour: dmenu spawns on second monitor (focused client).
	Now: dmenu spawns on specified monitor (first).

 .SH DESCRIPTION
-.SS Overview
-dmenu is a generic menu for X, originally designed for
-.BR dwm (1).
-It manages huge amounts (up to 10.000 and more) of user defined menu items
-efficiently.
-.SS Options
+.B dmenu
+is a dynamic menu for X, which reads a list of newline\-separated items from
+stdin.  When the user selects an item and presses Return, their choice is printed
+to stdout and dmenu terminates.  Entering text will narrow the items to those
+matching the tokens in the input.
+.P
+.B dmenu_run
+is a script used by
+.IR dwm (1)
+which lists programs in the user's $PATH and runs the result in their $SHELL.

+.TH STEST 1 dmenu\-VERSION
+.SH NAME
+stest \- filter a list of files by properties
+.SH SYNOPSIS
+.B stest
+.RB [ -abcdefghlpqrsuwx ]
+.RB [ -n
+.IR file ]
+.RB [ -o
+.IR file ]
+.RI [ file ...]
+.SH DESCRIPTION
+.B stest
+takes a list of files and filters by the files' properties, analogous to
+.IR test (1).
+Files which pass all tests are printed to stdout. If no files are given, stest
+reads files from stdin.
+.SH OPTIONS
+.TP
+.B \-a
+Test hidden files.
+.TP
+.B \-b
+Test that files are block specials.
+.TP
+.B \-c
+Test that files are character specials.
+.TP
+.B \-d
+Test that files are directories.
+.TP
+.B \-e
+Test that files exist.
+.TP
+.B \-f
+Test that files are regular files.
+.TP
+.B \-g
+Test that files have their set-group-ID flag set.
+.TP
+.B \-h
+Test that files are symbolic links.
+.TP
+.B \-l
+Test the contents of a directory given as an argument.
+.TP
+.BI \-n " file"
+Test that files are newer than
+.IR file .
+.TP
+.BI \-o " file"
+Test that files are older than
+.IR file .
+.TP
+.B \-p
+Test that files are named pipes.
+.TP
+.B \-q
+No files are printed, only the exit status is returned.
+.TP
+.B \-r
+Test that files are readable.
+.TP
+.B \-s
+Test that files are not empty.
+.TP
+.B \-u
+Test that files have their set-user-ID flag set.
+.TP
+.B \-v
+Invert the sense of tests, only failing files pass.
+.TP
+.B \-w
+Test that files are writable.
+.TP
+.B \-x
+Test that files are executable.
+.SH EXIT STATUS
+.TP
+.B 0
+At least one file passed all tests.
+.TP
+.B 1
+No files passed all tests.
+.TP
+.B 2
+An error occurred.
+.SH SEE ALSO
+.IR dmenu (1),
+.IR test (1)
