Yes, but because they could previously be individually selected, I gave the 
users of my application the option of setting bk_parens and/or bk_braces, 
separately from choosing POSIX or Perl semantics.  It seems that syntax and 
semantics are no longer orthogonal.  I don't have strong feelings about 
that, but just wanted to check that it was intentional, before hacking the 
application.

Thanks,
