+ -i	Replace stdin (default)
+ -o	Replace stdout (default)
+ -e	Replace stderr (default with feature REPLACE_STDERR)
+ -I	No replace stdin
+ -O	No replace stderr
+ -E	No replace stderr (default without feature REPLACE_STDERR)

+Examples:
+	$ sink -ioe cat	# sink steam in,out,err
+	$ sink -iOE cat	# sink stream in. keep stream out and err
+	$ sink -O cat	# sink default streams, but keep out
+	$ sink -E cat	# sink default streams and err
+Redundant examples:

+	$ sink -Ii cat	# sink default streams except in (i comes after the redundant I)
