-       Example:
+       The audio format specifier is a regular expression which
+       specifies the set of audio formats for which this option
+       should apply.
+
+       If any receiver options are present, the whole receiver
+       argument must be quoted:
 
                -r 'mp3:http -i my.host.org -p 8009'
+
+       Since a single dot '.' matches the name of any audio format,
+       specifying '.' instead of 'mp3' above activates the http
+       receiver for all audio formats.
