bugs and misfeatures in polr(MASS).... fixed!

Great!
You can skip my question about s0 though, I found where it is being used, 
but I still struggle with the code and convergence problem.

I also found something here
http://biostat.mc.vanderbilt.edu/wiki/pub/Main/CharlesDupontStuff/newPolr.R
that seems like someone tried to fix it, but with this code I get mu
starting values out of range, nor do I get it right when I try to force
starting values.

If you got your code to work fine, you might have the answer to my problem.
If you want, maybe you could post your whole *fixed-polr.R*? :-)



I also can't see where the new object s0 is used in the old code?
