Attached v6j.

* marked arrays as "static const" rather than just "static"
* ran pgindent
* changed data types where appropriate (uint32->pg_wchar)
* modified perl code so that it produces code that's already pgindented
* cleanup of perl code, removing unnecessary subroutines and variables
* added a few comments
* ran pgperltidy

Some of the perl code working with ranges still needs further cleanup
and explanation, though.

Also, I ran some of my own simple tests (mostly ASCII) and it showed
over 10% speedup. That combined with the smaller table sizes makes this
well worth it.
