[R] R2WinBUGS is broken

[Uwe Ligges]

Dear John,

this is a new bug caused by a side effect from a new bugs.log function 
by Jouni Kerman that improves many other things. I have fixed it in the 
master sources on sourceforge right now and a bugfix release will appear 
on CRAN within a couple of days.

Best,
Uwe Ligges
