I only meant that the python's idea of Other_ID_* should be  
automatically generated from the unicode data file, so that when  
someone upgrades python's database to Unicode 5.1 (or whatever), they  
don't forget to update a manually copied Other_ID_* list as well.

I was voicing my support for your plan, in contrast to Talin's  
comment that perhaps a more conservative subset would be good.
