+ * OPTP_MIDLONG allows '-display foo' -like args but disables chaining
+ * 		of single-letter options. X programs should probably use this.
+ * OPTP_IMMEDIATE allows immediate arguments (-I/usr/include) (and disables
+ *		chaining and midlong options).
+ * OPTP_NO_DASH is the same as OPTP_CHAIN but allows the dash to be omitted
+ * 		for 'tar xzf foo' -like behavior.
+ * Long '--foo=bar' options are supported in all of the modes.
