[Mike G. v. a. <we...@ma...>]

Log Message:
-----------
Corrected documentation for the ?{4.56:%0.2f} and !{4.5645:%0.2f} constructions --
their behavior had been reversed.  Indicated that the !{ } construction is 
deprecated since it behave just like {4.5645:%0.2f}

 Two additional legacy formatting constructions are also supported:
 
-C<?{$c:%0.3f} > will give a number with 3 decimal places and a negative
-sign if the number is negative, no sign if the number is positive.
-
-C<!{$c:%0.3f}> determines the sign and prints it
-whether the number is positive or negative.
+C<!{$c:%0.3f} > will give a number with 3 decimal places and a negative
+sign if the number is negative, no sign if the number is positive.  Since this is 
+identical to the behavior of C<{$c:%0.3f}> the use of this syntax is depricated. 
+
+C<?{$c:%0.3f}> determines the sign and prints it
+whether the number is positive or negative.  You can use this 
+to force an expression such as C<+5.456>.
