Since I had already a branch open which was fixing some other issue in 
erl_types.erl, I've decided to use that branch for including those fixes 
too.  I know it's not the proper way of doing things, but it's extremely 
cumbersome to maintain different versions of erl_types...

The changes that fix these are here:

   git fetch git://github.com/kostis/otp.git list_to_bitstring

The last commit fixes the issue reported by Peer.
The previous commits refer to erlang:list_to_bitstring/1.
