Copperbox revision 471.

With the machinery from the last few commits, I've now been able to implement the runOn parser combinator - this repeatedly parsers until the end of a range. A range will usually be a table - in the the table directory, tables have an offset and a length to locate them in the input stream. An example, one of the formats for the post table has a runOn of Pascal strings until the end of the table to give Unicode names.
