Want to poke at the network package a bit

[Bryan O'Sullivan]

As part of a project I'm working on, I have a need to add some IPv6 
support to the network library.  I'd like to clean up the haddocks (or 
indeed write some in the first place) as I go.

But before I start, I notice that the source has some peculiarities, 
such as explicit line number pragmas that are all wrong, making the 
process of finding errors unnecessarily interesting.  Is there any 
reason I shouldn't nuke them as I go?
