 The statistical outcome of this option should not be overlooked. Because
 \fBzzuf\fR cannot know the nature of the input data beforehands and must
 fuzz it even if only one byte of data was received, protecting characters
 may change the meaning of the \fB\-r\fR flag depending on the data being
-fuzzed. For instance, asking to fuzz 1% of input bits and to protect
-lowercase characters (using '\fB\-r 0.01 \-P a-z\fR') will result in an
