+  -m  Job control is enabled.
+  -n  Read commands but do not execute them.
+  -o option-name

+
+/* DYNAMIC VARIABLES
+
+   These are variables whose values are generated anew each time they are
+   referenced.  These are implemented using a pair of function pointers
+   in the struct variable: assign_func, which is called from bind_variable
+   and, if arrays are compiled into the shell, some of the functions in
+   arrayfunc.c, and dynamic_value, which is called from find_variable.
+
+   assign_func is called from bind_variable_internal, if
+   bind_variable_internal discovers that the variable being assigned to
+   has such a function.  The function is called as
+	SHELL_VAR *temp = (*(entry->assign_func)) (entry, value, ind)
+   and the (SHELL_VAR *)temp is returned as the value of bind_variable.  It
+   is usually ENTRY (self).  IND is an index for an array variable, and
+   unused otherwise.
+
+   dynamic_value is called from find_variable_internal to return a `new'
+   value for the specified dynamic varible.  If this function is NULL,
+   the variable is treated as a `normal' shell variable.  If it is not,
+   however, then this function is called like this:
+	tempvar = (*(var->dynamic_value)) (var);
+
+   Sometimes `tempvar' will replace the value of `var'.  Other times, the
+   shell will simply use the string value.  Pretty object-oriented, huh?
+
+   Be warned, though: if you `unset' a special variable, it loses its
+   special meaning, even if you subsequently set it.
+
+   The special assignment code would probably have been better put in
+   subst.c: do_assignment_internal, in the same style as
+   stupidly_hack_special_variables, but I wanted the changes as
+   localized as possible.  */
