Files should not have two or more consecutive blank lines.
Reasoning
This is not a technical concern, but you can improve the odds of others reading and liking your code by making it easier to follow.
Refactoring Proposal
elvis should warn that multiple blank lines are found in a given file (even if they are made up of trailing whitespace)
Options
max_lines (defaults to 1) should determine the number of consecutive blank lines that are allowed (1 means that a warning would occur for 2 blank lines in a row).
Note: if you're using a formatter, this could/should be a concern for it, also.
