Random pep8 fixes!

This patch merely fixes a selection of files to the point where
pep8 1.3.3 is happy. Most of the errors are indentation related to
continued lines (E126, E127, E128), bracket positions (E124) and the
use of backslash (E502).

Patch 2 fixes David's comments regarding backslash and an odd comment
 - thanks David!
