[Haddock] Contents page wibbles

[Simon Marlow]

I just noticed a couple of wibbles in the layout of contents pages that 
could be tidied up:

  * the package description at the top, and its heading, is indented more
    than the "Modules" heading and the list of modules.  I think these
    should be indented equally.

  * in the module tree, when a subtree has a few modules some of which
    have children, the ones with children are indented a tiny bit more
    (a few pixels) than the ones without children.  Perhaps due to the
    collapse button?

This is with FF 3.6.  Here's a copy of the base package processed with 
the new Haddock to illustrate:
