description:
Detect more ad clauses, pick more duplicates.

If there are notices that differ in the final dot, prefer the version
with the dot.  Sort "by the" enries after all other "by Name" entries.
With the corresponding re-ordering of the legal.common the output of
this script is getting useful again.
