Preserve all blank lines in code blocks.
Fixes #183. Finally got this working properly. The key was
using a regex substitution with non-overlapping matches that
removed all whitespace from the begining of *all* blank lines
when normalizing whitespace.
Once I got that, I could simplfy the EmptyBlockProcessor
and easily output one or two blank lines appropriately.
A blank block gets two new lines (`'\n\n'`), while a
block which starts with a newline gets one.
