I don't think human-readability is necessary for an RBL. And the bitmask 
format is transparent to a program and is more efficient for a program 
to use. Making it readable to a human could be the task of a query 
program that is designed to be used by a human. For example, if you have 
a web page form to query the SURBL it could accept a host or domain name 
or a URI and display in a list form instead of as a bitmask.
