SYNOPSIS
	void input_to(string fun)
	void input_to(string fun, int flag, ...)

DESCRIPTION
	Enable next line of user input to be sent to the local
	function fun as an argument. The input line will not be
	parsed, only when it starts with a "!" (like a kind of shell
	escape).
	
	Note that fun is not called immediately but after pressing the
	RETURN key.
	
	If input_to() is called more than once in the same execution,
	only the first call has any effect.
	
	If optional argument flag is non-zero, the line given by the
	user will not be echoed, and is not seen if snooped.

	The optional 3rd and following args will be passed as second and
	subsequent args to the function fun. (This feature is was
	added only recently, to avoid the need for global variables)

EXAMPLE
	void func() {
	   ...
	   write("Please enter your name:");
	   input_to("enter_name");
	   ...
	}
	enter_name(string str) {
	   write("Is '"+str+"' really your name?? *giggle*\n");
	   ...
	}
	
	When reaching the input_to() statement the driver
	continues the function func() but also asks the user for
	input. If you entered whatever is asked and press RETURN the
	driver will invoke the enter_name() function with the
	string you entered as argument to it.
