[FIX] spurious whitespace when saving unchanged blocks

With the new eyaml parser from I'm seeing the cipher text indented each time on the blocks you don't update

eyaml -i test_input.yaml

update a random key just to trigger a file diff on save, and diff, and notice the blocks are now more indented.

I can see eyaml/parser/encrypted_tokens.rb to_encrypted() adds this indentation, and I'm considering suggesting just dropping it. I'm still unwinding these changes from my 1.3.4 fix to find a better solution.

ciphertext = @cipher.gsub(/\n/, "\n" + @indentation)
