Making tests care about whitespace

When testing #19 I found that the tests were mistakenly ignoring some
whitespace changes. I've enabled whitespace checks and had to update the
tests because my editor likes newlines at the end of files and removes
whitespace at the end of lines. To make the test files easier to manage,
I've modified some scenarios to still test for the feature but also work
with the whitespace modifications that editors would perform.
