Title: Cosmetic fixes in block_format AM helper method + test

The block_format ActionMailer helper method was introduced at the end of 2009 - 63b124b043dec036403f9a88aeafdf99669064e0 and tested bd96614101262e0ad0cc176ed8e2d95a5c17936b.

I'm not sure that block_format is widely used but I think we can make it better.
I suggest to make small changes in paragraph splitting technique and increase test coverage.
