[erlang-patches] Enhancement of erl_prettypr

[Henrik Nord]

Hi

We have decided to drop this patch.

we will also remove similar behaviour from erl_pp (which is the OTP 
equivalent to erl_prettypr), It does the wrong thing, and it does it in 
the wrong way at this moment.



Thank you for your contribution!
