How about

 if ($#ARGV < 0) {
 	print "usage: $P [options] patchfile\n";
 	print "version: $V\n";
 	print "options: -q           => quiet\n";
 	print "         --no-tree    => run without a kernel tree\n";
 	print "         --terse      => one line per report\n";
 	print "         --emacs      => emacs compile window format\n";
 	print "         --file       => check a source file\n";
 	print "         --strict     => enable more subjective tests\n";
 	print "         --root       => path to the kernel tree root\n";
+	print "When patchfile is -, read standard input.\n";
 	exit(1);
 }
