Bug in Cabal creating user package.conf

[Ashley Yakeley]

I don't know if this has already been mentioned, but there's a bug in 
Cabal which I noticed when I tried to configure a package:

  $ runghc Setup.hs configure
  ...
  configure: Reading installed packages...
  cannot parse package list

It turns out Setup created a user package.conf consisting of the two 
characters "[]" without a newline, which it was then unable to parse. 
Adding a newline fixed the problem.
